A first refill
Your manual says 2.0 mm and you want a short card that loads without a fight. The Oregon 69-356-Y is round yellow line, 15 m, at £3.59, with a one-year warranty. It is about 24p a metre.
The best 2 mm trimmer lines, compared.
Top pick: Viabrico square 2.0 mm Best value: Zeqeey round 2.0 mm, 150 m – About 10p a metre at £14.99, the lowest rate among lengths that agree with themselves. Updated October 2026.
A 2 mm trimmer line is nylon about 2.0 millimetres thick that a strimmer head spins through grass and light weeds. You use it when the manual allows 2.0 mm: thicker than much 1.6 mm line, and thinner than the 2.4–3.0 mm line for rough petrol work in the [3 mm trimmer line](/hub/lawn-and-garden-equipment/trimmer-line-3mm) comparison. Check the printed diameter, whether the eyelet takes the shape, and whether the nylon is still flexible. A 15 m card costs more per metre than a 100–150 m reel. Rank only reels whose title says 2.0 mm.

Question 1 of 2
How often do you cut?
Viabrico model US-080in-1.35LB is the only square line in this set, stated as 2.0 mm and also as .080 inch, orange, at £11.99. The bullet says 130 m and the title says 425 ft, which is about 130 m, while a UK review describes about 390 m. The technical weight is 730 g, which does not match the 1.35 lb printed on the title. UK reviews praise the cut and the visible offcuts, and they also say it is hard to load and can make a small strimmer hot. A STIHL 36 V owner said square fitted and was the maximum that head would take. The 4.6 score from 7,333 ratings is not proof that every review concerns this length. Buy it only when your head allows a square profile and you can live with an unsettled metre count.
Pros
Cons
Best for: A head whose instructions allow square 2.0 mm, if you can accept that the metre count is disputed
Less suitable: A round-only eyelet, a small strimmer that already runs hot, or anyone who needs a known length
Specifications
Common questions
Is this line round?
No. The bullets call it square, 2.0 mm, orange.
How long is the spool?
The bullet says 130 m and the title says 425 ft, which is about 130 m. A UK review says the description stated 380 m and they found about 390–395 m. The extract does not settle it.
Will it load easily?
A UK review says it is extremely thick and difficult to load, then cuts well. Another says a cheap strimmer gets hot with it. A STIHL 36 V owner said square fitted and was the maximum that head would take.
Across 4,712 amazon.co.uk reviews at 4.6 out of 5, Oregon part 69-358-Y is a round yellow 2.0 mm line sold as 127 m for £16.07, with the unit count printed as 126.98 m. That is about 13p a metre, and the listing adds a one-year manufacturer warranty plus a claimed donut spool. Most of the first 50 UK reviews call it strong on grass and nettles. One reviewer says it breaks easily, and another says a water soak stops it binding. A further owner preferred it to STIHL 2 mm line that had welded in the head. It is the top pick when you cut often enough that a 15 m card would run out and you want a named round part. Leave it for a single short edge that the £3.59 card already covers.
Pros
Cons
Best for: Regular edging where a named round Oregon part and a long reel matter more than the lowest till price
Less suitable: A single short job that a 15 m card already covers
Specifications
Common questions
How long is this Oregon reel?
The title says 127 m. The unit count is 126.98 metres. The model is 69-358-Y.
What shape and colour is it?
Round and yellow. A bullet claims a donut-style spool to reduce tangling.
What do UK reviews repeat?
Most of the first 50 call it strong and a good fit. One says it breaks easily. Another says a water soak stops it binding. One owner preferred it to STIHL 2 mm that had welded in the head.
FEPITO’s listing is round green nylon stated as 2.0 mm by 100 m, at £8.99, about 9p a metre if the gauge on the title is what arrives. There is no model number and no warranty line. Reviews say the line arrives as a loose hank that tangles unless you rewind it onto a drum, and that dry line is brittle until it is soaked. The 4.5 score from 7,661 ratings is the largest file in this set, though it may pool other gauges: one UK review describes a 1.6 mm FEPITO reel under this ASIN. Praise centres on metres for the money. One review says it breaks within a few minutes. Take it only if you will rewind a hank and you can check the diameter on the packet.
Pros
Cons
Best for: A buyer who will rewind a hank onto a spool and will check that the delivered line is 2.0 mm
Less suitable: Anyone who needs the 7,661 ratings to refer only to this 2.0 mm reel
Specifications
Common questions
Is this definitely 2.0 mm?
The title and size line say 2.0 mm x 100 m. One UK review describes receiving a 1.6 mm x 100 m FEPITO line, so the star pool may mix gauges.
How is it packed?
Bullets do not mention a donut. UK reviews say it arrives as a loose wind and tangles unless you rewind it onto a drum.
What do reviews say about snapping?
Praise centres on metres for the money. Complaints say it is brittle until soaked, and one review says it breaks within a few minutes.
Oregon part 800002 is round 2.0 mm line, 15 m, at £6.99, about 47p a metre, with the country of origin given as France. The bullets say nylon with aluminium particles and claim up to 25 percent more runtime and up to 10 percent less noise than standard round line. Those percentages are the maker’s own claim, not an independent test. The 4.5 score from 1,103 reviews splits: some owners say it outlasts cheap nylon, and others say it still breaks after a soak, including half a 15 m roll in one garden. Warranty is not stated, and the colour field on the extract reads blackone. It is the short pack marketed at battery tools up to 40 V. Leave it when you are buying metres, because the plain 15 m Oregon card costs less than half as much.
Pros
Cons
Best for: A 15 m round refill on a cordless trimmer whose manual allows 2.0 mm, if you are buying the particle claim rather than metres
Less suitable: Anyone choosing on pence per metre, or a head limited to 1.65 mm
Specifications
Common questions
What is special about this 15 m Oregon line?
The bullets say nylon with aluminium particles, and claim up to 25 percent longer runtime and up to 10 percent less noise than standard round line. Those figures are the maker’s claim.
Did UK reviews agree it lasts?
Some say it outlasts cheap nylon. Others say it breaks often, including after a soak, and that half a 15 m roll went in one garden.
Where does the listing say it was made?
Country of origin is France. The colour field reads blackone.
SOL part 700151SOL is two green 20 m packs, 40 m in total, at £5.99, about 15p a metre. The listing does not name the shape or the polymer, and it does not state a warranty. It claims petrol and electric use, and it prints a 10,000 RPM field even though a reel has no motor. The 4.4 score from 2,563 reviews mostly describes a strong line that is easy to see and a fair price. One review used about 15 m on the edges of an 8 m by 4 m garden in a single session. It suits you when you want more metres than a 15 m card and the eyelet does not demand a named profile. Leave it if the head specifies round or square.
Pros
Cons
Best for: A mid-length refill when you do not need the packet to name round or square
Less suitable: A head whose eyelet or manual names one profile
Specifications
Common questions
Is the SOL line round or square?
The extract does not say. It only states 2 mm heavy-duty strimmer wire.
How much line is in the pack?
The title says two packs of 20 m, 40 m in total. The size field also reads 20 m x 2 mm.
What did buyers say about breakage?
Several UK reviews call it strong and easy to feed. One UK review used 15 m on the edges of an 8 m by 4 m garden in one go.
Oregon part 69-356-Y is a round yellow 2.0 mm line, 15 m, at £3.59, which works out at about 24p a metre. The listing gives it a one-year warranty, a 60 g pack weight, and an economy role for light trimming of medium to long grass. Among 1,361 reviews the score is 4.4 out of 5. UK comments in the extract mostly call it strong after a soak of about two hours, which is reviewer practice rather than a printed instruction. One Flymo owner says it snaps, and one owner had to stretch a curly end before it would feed. The low shelf price suits a first refill on a head that already allows 2.0 mm. It is a poor rate per metre if you trim every week.
Pros
Cons
Best for: A light trim on a head that allows 2.0 mm, when you want a known Oregon card rather than a bulk reel
Less suitable: Weekly cutting, where the pence per metre on a 15 m card adds up
Specifications
Common questions
What diameter and length is this Oregon pack?
The title and the item diameter say 2.0 mm, and the item length is 15 metres. The model is 69-356-Y.
Does the listing tell you to soak it?
The bullets do not. UK reviews in the extract say to soak it for about two hours so it is less brittle.
Is there a warranty on the listing?
Yes. The extract says a 1 year manufacturer warranty.
Zeqeey model 3406130101 is round green nylon stated as 2.0 mm by 150 m, and also as 492 ft, at £14.99. Those two length figures agree, so the reel is about 10p a metre on a spool. The bullet says line that has been stored should soak for 24 to 48 hours before use. Origin and warranty are not stated. The 4.4 score comes from 254 ratings, and the extract includes United States and Canada texts as well as UK ones. UK comments call the thickness right and the value fair, while one STIHL owner said the cord was brittle and the diameter too big. It is the best value in this set when you want a long round reel whose metre count matches itself. Leave it if you need a named Oregon part or a file that is only UK opinion.
Pros
Cons
Best for: A long round refill when you want the lowest pence per metre among listings whose length agrees with itself
Less suitable: A buyer who needs a named Oregon or STIHL part, or reviews that are only from the UK
Specifications
Common questions
Does the packet say to soak the line?
Yes. The bullet says prolonged storage makes the line brittle, and to soak it for 24–48 hours before use.
Is 150 m the same as 492 ft?
The title prints both. 492 feet is about 150 metres, so those two figures agree.
Are all the reviews from the UK?
No. The extract includes United States and Canada texts as well as UK ones. One UK STIHL owner said the cord was brittle and the diameter too big.
For this comparison we read the seven amazon.co.uk listings whose titles say 2.0 mm, and the public UK sources below. Each score is out of 100. A large review count that also describes another gauge scores low. We did not run a laboratory test. Shelf prices were read on 16 October 2026.
Stars on this reel
30%Up to 30 points for the Amazon star line only when the review texts are about this 2.0 mm reel. A large count that also describes another gauge scores low.
A listing you can load
25%Up to 25 points when the page names a diameter, a shape, a length that agrees with itself, and a pack you can load.
Pence per metre
25%Up to 25 points for pence per metre against the usable length. A length that clashes cannot earn a full value sum.
Review comments
20%Up to 20 points for review sentiment, with deductions for snapping, brittle dry line, a tangled hank, a hard load, and mixed-country files.
Match the diameter in the manual, then the shape the eyelet takes. Length sets the price per metre. A star count is only useful when the reviews are about this 2.0 mm reel.
A 2 mm trimmer line is nylon about 2.0 millimetres thick. A strimmer head spins it through grass and light weeds. You buy it when the manual allows 2.0 mm. It is thicker than much 1.6 mm line and thinner than 2.4–3.0 mm line sold for rough petrol work. Rank only reels whose title says 2.0 mm. Packs of 1.6 mm, 2.4 mm, 2.5 mm and 3.0 mm are the wrong diameter for this table. STIHL CF3 Pro cruciform 2.0 mm is sold on stihl.co.uk and is not an amazon.co.uk row here.

The size in the instructions wins. A petrol manual can say 2.5 mm while a STIHL AutoCut 2-2 takes 1.6 mm and 2.0 mm. Universal on a packet does not change that.
A reel has no motor. A 10,000 RPM field on the SOL listing, or a runtime percentage on Nylium, is not a measurement of the nylon.
Dry line snaps. STIHL UK says 12–24 hours. The Zeqeey listing says 24–48 hours for stored line. A tangled hank is the other way a new reel fails before it cuts.
Start with the diameter the manufacturer designed, then the shape the eyelet will take. Electrical Safety First says use the size in the instructions. In this set every title says 2.0 mm or 2 mm, which is the same gauge, but that does not mean every strimmer accepts it. A STIHL AutoCut 2-2 is 1.6 mm and 2.0 mm. A petrol manual can say 2.5 mm.
Length sets the price per metre more than the brand. On 16 October 2026 the Oregon 15 m card is £3.59, about 24p a metre, and the Nylium 15 m blister is £6.99, about 47p a metre, the dearest rate here. SOL is two 20 m packs, 40 m, at £5.99, about 15p a metre. FEPITO states 100 m at £8.99, about 9p a metre only if 2.0 mm arrives, and one UK review in that pool describes a 1.6 mm reel, so that rate does not take the best-value place.
Three typical situations, each with a recommendation from this comparison.
Your manual says 2.0 mm and you want a short card that loads without a fight. The Oregon 69-356-Y is round yellow line, 15 m, at £3.59, with a one-year warranty. It is about 24p a metre.
Oregon puts battery grass work in 1.6–2.4 mm and heavy weeds in 2.4–3.5 mm. The Nylium 800002 is a round 15 m pack marketed for battery tools up to 40 V, at £6.99. Leave it if the head is limited to 1.65 mm.
A 100 m reel or longer is cheaper per metre if you will wind a hank onto a spool. The Oregon 69-358-Y is 127 m at £16.07, about 13p a metre, with a named round part and a one-year warranty.
For regular cutting, the top pick is the Oregon 69-358-Y: round 2.0 mm, 127 m, £16.07, about 13p a metre, 4.6 from 4,712 reviews, and a one-year warranty. Sampled UK texts are about this reel. The best value is the Zeqeey 3406130101 at £14.99 for 150 m, about 10p a metre, where 492 ft agrees with 150 m. FEPITO’s arithmetic is about 9p a metre and does not take that place, because one UK review in that pool describes a 1.6 mm reel.

Zeqeey round 2.0 mm, 150 m
About 10p a metre at £14.99, the lowest rate among lengths that agree with themselves.
