This trimmer/edger replaced a Ryobi that wore out. I’ve owned B+D corded trimmers in the past—they just keep getting better with each model.
My primary use for the edger is maintaining the lines of my backyard labyrinth-900 linear feet, so the edger gets a good workout. The light weight makes it easier to control. It uses less trimmer line than anything I’ve used before, so the OEM line (which I recommend) won’t break the bank.
The Ryobi became difficult to switch between trimmer and edger because of its design. This B+D has a much better way of moving the head.
I also use it for a second house with heavier st agustine turf and the power is just sufficient, though it takes two batteries to finish.
After nine months of operation I have no problems.

Works well for home use
This is a great trimmer for home use. It's light, can do both trimming and edging, and has improved significantly over the previous model.The cordless concept gives you a lot of freedom. I have a corded edger with a blade and it's great for the really challenging parts of the lawn, but nothing beats the convenience of this cordless model.How well does it trim?For a home with a front and back yard (probably around 4000 sq ft lawn space) I found the 3Ah battery just enough to cover both yards if using a judicious mix of the two power settings. The low power setting is fine for most of the trimming and even some of the edging, but I use the higher power setting for thicker growth. This is for St. Augustine grass common in the south. If you have hardier substances to cut or if you need to use the higher power setting more than I do you may have to charge in the middle of the job and it does take a while to charge an empty battery. You can also buy additional compatible batteries on the Black and Decker 20v systems on Amazon which I would recommend for those with larger/tougher jobs.Which one is for you?The biggest differences with this model series are the batteries they come with and the string feed mechanism. I've included a chart to help understand the differences between the models. Some thoughts:- The basic 522 and 523 appear to be physically identical trimmers except for the string feed. The 522's is automatic, the 523's is manual. My old 400 had an automatic feed that worked but there were times I would have liked to have been able to feed it when the automatic didn't trigger.- The 523 appears to be sold in two options (at least it was when I bought mine). One option comes with a 3Ah battery, the other comes with a 1.5Ah battery. The bigger battery is heavier but lasts longer. If you have a smaller lawn, or you want the lightest weight, maybe the smaller battery unit is better for you. Although the unit is not heavy, you may feel it after using it for forty minutes. Again, if battery life is an issue, Amazon sells additional batteries separately, and they're compatible with the whole line of Black and Decker devices including cutters, drills, and more.- The 525 seems to be identical to the 523 but comes with a choice of either a 3Ah battery or two 1.5Ah batteries.- The entire 500 series (522, 523, etc) are a big improvement over the 400 series due to modifications to the trimmer/edger conversion mechanism and also the change of the auxiliary handle's friction clamp to instead a fixed pivot point on the handle assembly. This makes the 500 series easier to use and more reliable.6-Jun-2019 update: Saw a bunch of negative reviews from people that had issues with quality control on their units. I don't doubt them. I had issues with the previous generation of this unit. All I can say is that even with issues, I got four years out of the previous model and this one so far has worked fine. Stories of the awful (and probably outsourced) support from Black and Decker are disappointing, but that's the price of dealing with some corporations.
