Iffy at best.
Thing works great if you have an infinite amount of line available. Automatically feeds when it shouldn’t. Runs out of line way too fast.

2nd one lasted longer than 1st
This is the 2nd B & D string trimmer I have owned, the first died in less than a year and this one lasted two years. I purchased the 2 year protection plan from Lowes and am trying to get yet another replacement. Between the two, Im soooo disappointed in B & D for their low, low quality of their products, and also to Lowes for their lack of knowledge of product warranty as well as their own replacement plans that they offer. I will stick with purchasing other brands at Home Depot.

Great value!
My last Grass Hog lasted more than a decade and this one feel just as sturdy. This one is much more powerful though!

Light weight & Easy to use
I love this machine. I have wrist problems and could not use my gas machine. This is perfect for me and very efficient.

Not bad for the money
Gets the job done but removing the bottom spool cap is a pain cuz the buttons to squeeze in are real small. Kind of fussing winding the line on the spool without tangles. Used for about 3 hours and it went through the full spool of line and had to re-spool several times but just partially since the line jams easily. I had the 2 line feed version for several years so can't complain.

Motor bearing/bushing issue
Trimmer worked great for 1.5 years. Not sure why motor bearings/bushings wore out. I kept all vent openings cleaned out to prevent overheating. Was using the mower attachment and the motor started making noise, slowing down and finally stopped working.

6.5 amp 14 inch trimmer/edger
I bought this to replace a gas trimmer only because at the time that I bought gas my left arm worked, now that it is inoperable I needed something lighter than the gas trimmer, so I looked for the best trimmer with the best reviews and the best customer buys, Black & Decker had just that. Being basically the middle of the summer, trimmers were a little hard to find, Menards took care of my needs, it was the last one with it being the display model, no box but, had the instructions I needed, to get started and to find this site. Black & Decker has once again made a great product, I have a leaf blower that they manufacture and it has preformed flawlessly. Black & Decker is the company that gets the job done the first time and with ease, oh and the price was better than what I thought it would be, Black & Decker is the winner!

I have a medium size yard and yet I was unanble to go half way around the perimeter without having to add line three times. I do not thing that could be considered normal usage.

Try something else
This trimmer uses too much line. Went through three reels (over $23) within 30 minutes of trimming. Also line feed keeps getting stuck.
Will need to buy something better.
