Works like original equipment
Size: 16 Line Spools+4 Caps
Seems to handle the same work load as the manufacturer part. Good quality fit and design. No problems installing the string on the trimmer head. Definitely worth the purchase.

It was delivered next day
Size: 8 Line Spools+2 Caps
If it's like the previous line I purchased, it's good.
Don't leave it in a hot garage, because the line will sometimes stick together when you get around to using it!
NOTE:
Again, I received this product YESTERDAY, and Amazon is sending me a survey today!! What AMAZON brain surgeon thinks that this is a good idea????
