With all the talk about leather hand guards and such, I thought I might chime in with my $.02. I don't use hand guards, but I do use a half cover for most rehearsals and any parades or concerts. I haven't used it very long, but so far, I really like it. It was about the same price as a set of guards, and the for varies from brand to brand, but it's unique. And more importantly, it works! For me, I'm really anal about any type of smudging on my instrument, so this was a blessing. The only compint I have is that I need to take it off every time I put my horn in the case. Maybe with a gig bag I could leave it on? Nonetheless, I really enjoy this. Anyone else have experience with these Euph diapers?
