Weak wire
The wire simply tore off every 3-5 minutes, this is nightmare. I wish there was a stronger wire.

Cordless Weed Trimmer
Using my weed trimmer for the first time. I was impressed with how light it was . As far as trimming, it performed well for the size yard that I have.
My previous weed trimmer was gas and heavier but this trimmer was just what I needed.. Also, this is my first cordless trimmer. I have used Black and Decker products in the past have have been pleased with how well they performed.

A Great Idea Not So Great execution
This is my third B & D trimmer. The first one died of old age. The second one, probably still under warranty, the spinner core oddly disconnected from the motor and just stopped turning.And I bought the "mower" attachment for it the wheels are too high (I lowered them) to effectively remove the weeds. For the 3rd bought a few weeks ago, the weed deflector didn't fit on all the way. Luckily I still had it from the second machine which fit perfectly. While I like the device in many respects, I have had issues with them.

Love the cordless
Easy to assemble. Easy to use. Only complaint is the safety button doesn't lock into place, so the button has to be held in while squeezing the trigger at the same time.

Good product
Great quality and ease of use. Bought it as a father’s day gift and he loved it as our old weed eater was on its final leg. The only problem is battery size, but paired with other B&D batteries it’s perfect

still hopeful
I absolutely love the weed wacker, but am very disapointed in the extra battery I paid for and still waiting for order#7040434697 weeks later that was definitely promised weeks ago.

I love the weed wacker, but still waiting for the extra battery promised and paid for weeks ago.

Been having this thing for at least 7 or 8 years. Batteries are a bit weaker and had to change the feed spool cover 4 or 5 times but this thing works great. Black and Decker has the most consistent line feed system I have found. Other trimmers I had I was constantly fighting with the feed line. This is the second B&and battery weed eater I have had and my next one will be as well. Only issue is I wish the batteries lasted a bit longer. I can weed eat and blow for about 30 minutes on the 2 batteries.

Light-weight, performs well
I bought this over a year ago and it is still going. I did have to buy an extra battery, but i have a bigger yard. I definitely would recommend this.

Great Trimmer!
This is my 4th Black & Decker Trimmer/Edger in the past 19 years, and my 2nd of this model. All of them have worked great. They're light weight, and perfect for my yard.

Battery life sucks
I can't even get 1/4 of my fence line done on a full charge, then I have to wait till the next day to finish the 1st half of my fence line. It takes the whole week to just do the fence line. By thevtime I'm finished it's time to start again. I found an adapter on Ebay that will let me put my 20/60 volt Dewalt battery on it and then I can do my fence line in 1 hour on 1st day!!
