Excellent basic, no frills
My first B&D lasted about 10 years, was a similar basic model, then what I replaced it with was more "advanced" and pure trouble, so was lucky to go back to basics and ditched the other new item.

Does the job!!
Performs VERY well! Great device for my small yard!

Hubby and I used to have a Stihl gas powered trimmer. It was strong and did the job well, but then it quit running (had for a long time. It was always too heavy for me to use as I am small framed and 112 pounds. I can handle this electric trimmer much better, though it's never been a chore I like! Hubby can use it quickly and it did work well, except for the fact that it went through quite a lot of string. Overall, good for the price.

I bought this Trimmer to replace a 13 yr old one that died. The price was right and it is easier to handle than the old one. It does a good job and it's nice that you don't have to bump it.

Served my purpose
My Black and Decker motor on my existing Trimmer/Edger needs to be changed . I purchased this trimmer to use in the meantime. It will suffice for now. Due to it needing an electrical cord to run, it is somewhat inconvenient for all areas. I will keep it even after I get motor for my original trimmer. This wasn't very expensive and was on clearance.

Good basic tool
Used for past year, 70x120’ lot w/house. Reliable, rewound new line snug - only one untangle. Great BANG for buck! And I’m 87.

This item is easily handled by all females within the household. After a little over a year I finally needed to replace the original spool. The spools are easily dropped into the bottom feeder. I love my trimmer!
