Customer Rating: - Dont need this one. Get loose cord and spool it up yourself
Spending 15 plus bucks on this is not worth it. You could instead get the nylon cord at homedepot or lowes and roll it up yourself.
People have tried it with various levels of success/failure but it does work for sure.

Customer Rating: - Auto Feed System Works Great!
These auto feed line trimmer spools work great with my 18 volt Black and Decker string trimmer. I have been using these spools since May 2006 and have not had any problems. We are now able to let our kids do the trimming, since this is an easy-to-use auto system that is light in weight and very quiet! As a result, I have not had to use my gas trimmer for the last two seasons. The spools last quite a long time, and we probably use three spools per year with an average yard. I am very inpressed with the spools and auto feed system, as I did not anticipate that it would work flawlessly. Great product.

Customer Rating: - Positive purchase.
I purchased these recently and the products were received as expected. I have used these before and they work well enough to get the job done for an electric weed eater.

Customer Rating: - Easy way to shop
Product was exactly what I needed, and after I searched my local stores for the replacement spools, unsuccessfully, I finally looked online and found it at a good price at Amazon, Thanks!
