    • Much tougher than I expecred.
Size: 3 lbs
I have a walk behind 6HP string mower that uses .155 line. I bought a roll of triangle yellow Ugly nylon style line from Sears 14 years ago when I got and that 100 ft. roll lasted a long time, but breakage and slip out was always a problem. It was soft, easy ro bend, and didn't really seat securely under the head clips. I thought this was just normal. I finally ran out. But after getting this Oreon Magnum line, my whole thought about .155 line changed. This is much much stiffer, thicker, a true square cut, and unless you hit actual small trees, does not break or pull out every 5 minutes. I beat the bonkers out of this stuff. If you hit small trees, it takes a beating but will break, but with protest It has a core you can clearly see. I am very amazed about how well this .155 line works. Some people mention getting .170 line for walk behind weeders. I imagine it would work real well if you could get it to insert by using a torch to soften the bend, but this .155 line fits quite tightly and securely. Not sure if .170 would pull into the head hooks. This .155 takes a pretty stiff pull and bend and to seat. Regarding using .170, you do need to have a limit on how much stress you put on the mower head. The replacement for a DR style trimmer head is close to $100. Secondly, the current price for this .155 for the amount you get is unbeatable. This roll is very big and will last till you die! It's a great buy currently. Not sure if the Platnum is as good from reading the reviews. But this stuff is impressive and still safe. ... show more

    • Very tough, made for the rough jobs
Size: 1/2 lb
We use a walk behind string trimmer that's very powerful. This is not a spool unit, you cut lengths of trim wire and feed it into holders. This stuff is very strong, I cut through tall grass, thick weeds, and even tree seedlings up to about an inch. Great stuff.

    • Super Heavy Duty Line!!
Size: 1/2 lb
If this line can fit in your trimmer head, and you need some heavy duty line. This 100% works!! I have a commercial duty Stihl trimmer with an Echo Speed Feed head. I had to modify the inner hub of the head to accept this thicker line by drilling out the hole to a larger diameter. This line is so strong my safety guard line trimmer has a hard time cutting it after feeding. I live in the country, not a huge property but have a riverbank, lots of wire fence line and plenty of oak trees.. this is the first time since I bought this property in 5 years that I trimmed the entire property in just one session. Mowed down heavy weeds and saplings with ease. Only had to bump the speed feed twice all morning! Super Heavy Duty Line!! ... show more

    • EXTREMELY DURABLE AND EFFICIENT.... FINISH IN HALF THE TIME!!
Size: 5 lbs
This line is very durable for heavy grass and weeds. Lasts longer than OEM trimmer line. The square shape takes more horsepower to rotate but cuts quicker and easier making up for slightly reduced RPMs. This line 'slices' through weeds and grass whereas round line tends to beat the grass and weeds. In addition this line moves the cut grass to the side and out of the way better than round line. Works well on tougher grasses that are more difficult to cut. 8/19/2019 addition In the fall we have a very tough grass (crowfoots grass and broadleaf signal grass). Both extremely difficult to cut... DR'S ROUND GREEN LINE JUST BEATS IT DOWN. This line actually cuts the grass... EASILY I MUST SAY... AND MOVES IT TO THE SIDE TO CONTINUE CUTTING. I DON'T CARE HOW OTHERS RATE THIS TRIMMER LINE BUT IF YOU WANT THE BEST... IT IS A LITTLE DIFFICULT TO INSERT IN THE DR head BUT ROUNDING THE ENDS MAKES THIS TASK MUCH EASIER. IT ALSO LASTS AND LASTS... DON'T THINK I'LL EVER SWITCH!! ... show more

    • Extremely loud high pitched whistling sound. Too stiff.
Size: 1/2 lb
I put this on, and the Husqvarna DR trimmer sounds absolutely terrible with this line. It seems to bog down slightly more with this line compared with the spiral line. And I have a theory, that this square line actually cuts more of the grass, instead of just blowing it around, so it uses more power actually cutting/shearing the plant vegetation. I am returning this product, because the machine is unbearable to use with this line. I've run the square line for about 30 minutes, and the high pitched whitsling from this square 0.155" line is so annoying it is literally ear piercing. I can't say for sure if the sound will go away, after the line has been used longer, and begins to stretch out and straighten out, or maybe I cut the pieces too long (almost to the edges of the plastic housing on the DR trimmer) and I haven't done a side by side test with the old line. But this is by far the loudest whistling I've ever heard from any power equipment before. It's literally a shrieking sound. They need to come up with some method of making the line more aerodynamic. I know Golf Balls are extremely aerodynamic, despite being a blunt object, and it's because of their holes. Perhaps they could make a trimmer line with a certain shape (like the Titanium line from Husqvarna) that would quiet the line down? Anyway, it doesn't matter how good it cuts. It sounds so loud, and is such a high pitched and loud whistling coming from this line, that I am returning it. It is very good line, and very strong, and cuts very well. But it is too loud. ... show more
