    Good = 2.4 mm line
  

*by M***R on Reviewed in the United States on August 2, 2016*

This is good quality trim line, (for the $) same 2.4 mm size as my roll of Stihl line.And doesn't seem to snap any more frequently then Stihl.When I purchased a Stihl weed wacker years ago, also bought Stihl lineand wasn't as happy with it as I expected.So purchased Echo's 'Cross Fire' nylon line which I like much better.It's thicker diameter and unique shape has been my favorite for many years.Crossfire cost more = but cuts better and lasts longer.I'm not sure of Echo's mm but it only takes 2 twelve ft lengths to refill the Stihl head.Rather than 2 fourteen ft with Stihl and Shakespeare.So yes this is a good line for the money, but very cheap packaging.And if you're wanting a line that doesn't snap often = there are stronger strengths of line.----------------------------------Googled Jarden & found that "Yard Gear is the world’s largest supplier of trimmer line and trimmer heads'And = Shakespeare® branded trimmer accessories are found exclusively at Lowe's.

Strong line that has performed well- nothing special, but it has lasted as long as other brands and cut well.

    Ultra durable filament
  

*by T***A on Reviewed in the United States on September 7, 2016*

This Ultra Cut filament from Shakespeare works great for grass trimming and edging. It's a little thick for my electric trimmer but feeds easily in my gas trimmer.I did manage to get it wound and fed into my electric trimmer and it worked really well except it wouldn't feed by bumping. I had to advance it manually. Fortunately, it's very durable and even on my large property, I only had to advance the string twice.With my gas trimmer, I had no problems at all. It gives a nice, clean cut and again, I didn't have to advance it very often. Good stuff.One star deleted because of the crappy, plastic container. It's thin and lets the filament get tangled.
