I like it. I first got it when I was working on a computer for years all day like you, then add doing other things, and I had trouble. The one thing, is that it does add some bulk in the glove thumb area, which I had to get used to at first (but not bad, and one has to get used to any new safety thing they add). It sure helped though.
I see that they have an open Wrist Thing, which wasn't available when I got my other one. I might just give that one a shot too since it's on sale right now. In the midst of more technical riding, I like more dexterity. I guess if I wore my other one all the time, I'd be used it and it wouldn't be an issue for me (as my knee & back braces aren't).
I even take my Wrist/ThumbThing shooting if we were going to be doing a long session (usually when going with friends and shooting a lot of rounds from different guns).
