Review on Mercer Industries 182020 Crimped Grinders by David Lesperance

I use these a lot, as mentioned wear safety glasses as the ends will loosen and fall off over time. This happens with any type of spoked wheel and I haven't noticed excessive breakage. I use it almost every day to clean various parts, hubs, silicone cases, etc. Be careful, move slowly and with control, and it's a great product for what you pay for.
