I have tried them when I had carple (sp?) tunnel. I think mine were a little too big so it made it hard to hold on to the equipment which just made matters worse. The ones I had were just gloves with gel in the palm area. It dampened the vibes good enough I guess. I got mine from Woodcraft.
Hello Solo - try a product called "Sorbothane" - the distributor up here is a company called Ergotech. I saw a commercial where you could hit your hand with a hammer and the glove would absorb the impact. They also use it as flooring covering where people like production-line workers have to stand all day on a hard floor and it's supposed to cushin the impact of their feet on the floor all day.

I bought a pair to try for lawn mowing. (36" walk behind) Just a simple pair from a safety supply catalog. They work great. My hands used to get numb for 30 min after mowing. Now they feel fine. So for my situation they did everything I had hoped for.
