[I] saw them at the Quilting Expo and thought they were cool, but a bit pricey. I explained the texture of the foam to my SO, and he brought back a bunch of the same stuff from his hunting range(don't know what they use it for). This stuff works GREAT!!! I was why given a pair of Machingers to use since then, and after 45 minutes my wrists broke out in a rash. I don't usually have sensitive skin to anything, but who knows. Anyway, I recommend the Bats!!!
