BLACK+DECKER String Trimmer, Electric Automatic Feed, 13-Inch, 4.4-Amp (ST7700)

September 2012 - After reading many of the reviews, I was hesitant to purchase this item. I started out with the battery model for the B&D trimmer and after charging 24 hours it worked for 15 minutes top. I returned the battery model and purchased the electric B&D model. I used it for the first time today and was able to complete an hour's worth of weed-eating and edging work. I was thrilled. I am a 55 year old woman and I find this trimmer easy to handle (except for the cord, but I don't mind that if it lasts more than 15 minutes.), light weight and quite powerful. My yard is 70' x 125' and I was able to complete almost all of the edging in a little over an hour. (I stopped because I needed a break, not because the trimmer lost power.)I also used all of the initial string and had to restring the trimmer with 0.065 string. This is usually my biggest test because I can never get the string on right. I followed all of the intructions and reloaded the string and was able to trim for another hour without fail. I hope and pray this trimmer continues to work. Will keep you all posted. EBApril 2013 - Season II - All is great. Today was our first real spring in Richmond, VA -- 90 degrees -- more like a shift from Winter to Summer instead of Spring. Anyway, I pulled the old B&D Electric Trimmer I purchased last year with my fingers crossed and to my surprise, it worked like a champ. I edged for over an hour --- that's my personal limit --- and all was fine. I must say, it is a lot better than the battery operated model. I changed the string with not problem and I didn't have any string problem until the end. I still have half of the yard to finish tomorrow, so stay tuned. If it gets me pass the more demanding part of the season, I'll give it a 5 Star because the first Spring cut after Winter is the worst. I was anxious but all worked just fine!August 2013 - Great Trimmer! I am going to order another just in case.May 2015 - Spring cleaning and lots of edging....Trimmer worked like a PRO! Trimmed 8750 sq/ft lawn plus flower beds. Worked continuously for 1.5 hours --- when I needed a break. All works well. I'm impressed and I'm ordering a new one today to keep on hand. Five years of heavy use is not bad.

Been using this for over a year. It's performed well through two seasons. It's very powerful, and easy to use. I mainly use it for grass but I've taken down weeds like they didn't stand a chance. I have not experienced any issues with this weed trimmer so far. I don't anticipate any problems with it anytime soon either. These work great and they're very cheap. Definitely worth the price.The last one I had (similar B&D) died most likely due to someone using it and not cleaning out the heat vents. If you buy one of these, take care of it. A little maintenance goes a long way. I used the last one for 5 years. The last season I had it, it did well every time I used it. I let someone else use it a few times, it melted. The whole casing was burning hot and covered in grass that was matted down to it.

This is by far the best trimmer I've owned in a long time. I've used it 5 times now to trim and edge my yard, and I haven't had a broken line yet, and it feed remarkably well. I am still using the line that was supplied on the spool, and that might be the reason it has performed so well. When it comes time to replenish the line to the spool, I'm going to try ensure that it is wrapped neatly. I think the real test will be on the replenished spool. So the jury is still out on that. But so far it has earned it's 5 star rating. Well done Black and Decker. And no....... I'm not one of those paid reviewers.**********************************************Review Update**********************************************Have been using this trimmer since Nov2015. If I could, I would give it TEN STARS ! This is by far the best trimmer I've had the pleasure of using, and I've used a lot of them. Am sorry to admit I have wrapped a few around the trunks of large sturdy trees in desperation. I've never once had to hassle with broken lines or failure to feed, and I'm working on my 3rd spool of line, 2 of which I wrapped. Everything eventually wears out, so I'm debating on buying another ST7700, for a spare. You never know when B & D will decide to change the model, and possibly not get it right the next time.

Bought this Black&Decker string trimmer when my old one (different brand) finally gave up the ghost. Couldn't be happier. It's more powerful than the old one, the string advances by itself (no need to bump it on the ground repeatedly), its light and easy to maneuver, and feels built to last. Always nice when a replacement tool turns out to be better than its predecessor. Haven't had any problems with flying debris hitting legs or face, but would recommend wearing glasses or some form of protective eye wear just in case.

Right out of the box the trimmer line would not auto feed. I took the spool apart, everything looked fine, re assembled and still no auto feed. UPDATE - turns out the trimmer line was rough and stuck together further into the spool. After throwing away half the trimmer line it worked. Then I found a smooth round .065 trimmer line worked fine after that. This trimmer has way more power than battery ones and is much lighter. Good buy for the price.
