I need to cut patio pavers and my old grinder burned out. So I bought this angle grinder. The build quality looks good. A little heavy after inserting the battery. (Compared to my previous wired one) But I get by with it with no issues. The extra weight helps keep the grinder stable. It's strong, I don't feel weak compared to my old Corder. This grinder has 10 cutting and grinding wheels which is good for a first time buyer. But since I already have a lot of hard drives, this is not very practical for me. It also comes with 2 thin/thick drive protectors. All in all a good coffee grinder. Powerful and easy to use. Would recommend.
