Review: 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 desertcart 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, desertcart 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.
Review: Love it - Very easy to use: twist the shaft to go from horizontal cutting to vertical; battery attachment couldn't be easier. However, recommend larger battery for all but tiny yards and requirements. It is light weight compared to the bulky electric cable or gas edgers. Trims both weeds and borders usually on low power. Has a higher power usage switch for stubborn weeds. This is designed as a grass edger, but as stated does light weeds as well, especially at higher power offering. It certainly would have now replaced my Stihl gas trimmer I needed 25+ years ago where I chopped down 4-6' weeds. Now that I am back to civilization and have just a grass property, this is fantastic. Stores easily in the golf cabinet in my garage that came with the house. I bought extra spools of cutting material, but haven't replaced the original yet after all Summer. The automatic spool advance works without any trouble as does the manual advance when desired. Couldn't be happier unless wife wants to do the outside trimming.

### ⭐⭐⭐⭐ Not the same power as a gas version, but enough advantages to make it something to consider.
*by S***C on August 23, 2017*

I recently had a two year old, $200 gas powered trimmer go out. Tried to get it repaired, but the motor had lost compression and was not economical to fix. Needless to say, I have been extremely dissapointed at the longevity I got out of that one and decided to explore some alternatives. I have just under a 1 acre lot, so quite a bit of edges to keep trimmed. After researching, it seemed like the main negatives to battery powered models are: 1. Batteries don't run very long in a cycle. 2. Batteries have a short lifespan. I ended up going with this model over the more expensive, but similarly specc'd Dewalt version when I found that there were replacement batteries available on Amazon at a reasonable price. The available/cheap replacement batteries take care of issue #2 for me. As far as #1 goes, the run time I get off a charge is acceptable. I only run it in the high power mode (power issued addressed next) and I comfortably get 20 minutes. I don't generally don't do the entire yard every week, so this is more than enough time for my needs. I presume that it would get substantially longer run times on the low power mode. My main complaint is something that wasn't on the original list -- lack of power. Even when I run it at the high power setting, it isn't anywhere near the level of a gas powered version. "That's not a fair comparison" you say? I disagree -- this is sold as a trimmer tool, and it should meet the performance expectations of that tool. Electric motors should be able to put out plenty of torque. Part of the power issue is that the string dispenser lets out only one strand instead of two that you normally see on a gas powered version. Even if it spun at the same speed/torque, it just doesn't have the same ability to mow down grass. That said, it does get the job done, albeit a bit slower than I'd like. Of course, this version has several benefits over a gas powered trimmer: It's lighter, it doesn't require me to maintain a oil/gas tank, it's easy to start, and the string dispenser is easy to change. Battery charging time is a non-issue for me, and the battery charger included is compact. If I can get a couple years out of this tool, I'll count it as a success.
