Review on Superb Wrench SPBW 1 Housing Diameter by Amrozi Papi

I've just received the Superb Wrench SPBW-1 for our standard 10" water filter housings. Although I didn't have to change the filter, I just had to try. Impressed, I slipped, turned it on and spun with moderate force. I cut my hand pretty badly on the side. I'm very glad I bought this. The price is small compared to the hassle of removing the filter housing from the wall and hitting it with a hammer. My only complaint is that the metal edges are too sharp. They cut and scratched the filter housing. I took 400 grit sandpaper and sanded them all. It took a few minutes but everything is much better now. enough body to be a problem. I hope the manufacturer doesn't take care of this before the sale, but it could be worse.
