I am a professional floorer. I've used every possible hearing aid. Among other things, I sometimes make my own from wooden blocks and carpet scraps. Most do their jobs well. But there are caveats to this statement. Some put their hands in the "strike zone" and anyone who breaks a finger or hand will be injured. Others fall apart or damage the flooring. It's never good. It's rare to find a tool that not only gets the job done, but does it well AND eliminates an entire step. Plus, it cuts installation time and is generally a pleasure to use. This is one of those tools. Instead of block and hammer, all you need now is this tool. No more hammer and block. That means less wear and tear on your body. Means faster setup time. Means less ground damage. .Well built. Works perfectly. Perfect weight and it prevents my hands from breaking. I can't say more than buy. This is a value that will pay off again and again. This is so great, I want more! Professional recommended!
