Black & Decker cordless weedwacker
It seems kind of chinzy for $100, I doubt it will last very long. It does an OK job on the light weeds. The battery doesn't last very long, so it is a good thing it came with 2. They take a long time to charge.

Works fine, but instructions were a little difficult to read
Product works as advertised, but the instructions for installation were a little difficult to read.

What you need, in a multipack, for a low price - perfect.
If this is the size and type of line your need for your trimmer, why not by a multipack? As long as your trimmer doesn't break, you know you'll need more; and you get them at a much cheaper price than buying one at a time.

Good product, also reasonably priced 3 spools to the package. Buying 1 spool at a time is more expensive.
