How this shipped was entirely suspect to me. It arrived in one of those lightweight gray plastic shipping bags. Inside the shipping bag was a brick of bubble wrap wound up with shipping tape. Inside that mess was just the bare tool case – with the tool and accessories inside.Other than a satisfactory performance, there is nothing much nice to say about this angle grinder. I'll highlight two main concerns:*) The tool I received was noticeably scratched up. It would appear to be used. And more concerning was the debris and hair sticking out from under the labeling on the batteries. See pictures.*) The batteries are even more suspect given that a minimally spent battery could never achieve a full charge even after six hours: the red light on the charger did not turn green. The implications of that are beyond my skill set, but it doesn't breed confidence at all.There are a lot of cordless angle grinders in this price range that are significantly better in my opinion. Look at those. You may not get two 4.0Ah batteries like you do with this one, but two batteries is not a reasonable trade-off for how sketchy this is.

I was really excited to get this grinder. I've wanted one for a while, but didn't want shell out big bucks for a DeWalt or similar brand. Although it is a cheaper no-name brand, I didn't think it could be too bad for occasional use. I was wrong.My first project was to trim a cutout in some 1/8" flexible edging. After charging up the battery to full, I put on the cutting wheel and went to town. To my surprise, I was only able to go about 1.5" in on my first cut and it died. I pulled the trigger again... nothing. I thought it was a bad battery, so I put a different battery in and it still did not work. I checked to see if the metal was binding the wheel and it wasn't.After waiting about 5-10 minutes. I pulled the trigger and it came back to life. I tried to cut again and it cut maybe an 1/8 and died again. I ended up using my corded grinder to finish the job, which it did with ease.My advice is this. Unless you are going to be angle grinding aluminum beer cans, stay far away. The lower price is not worth the hassle of taking the risk and having to return it.

I started using this to prep some mild steel for welding. I stalled this grinder out repeatedly and I was not exerting much pressure. I picked up my DeWalt 20 volt cordless grinder and finished the job with no problems. This tool may seem like a bargain, but it is under powered big time. You don't always get what you pay for, but you always pay for what you get. Buy something else.
