Just added tonight after doing an FeS test! These are great, why? They really are nice, the design (I tested the wide version) allows for full use of the hand and open access for the thumb. It is easy to adjust of the move, and can be rolled out of the way easily if you desire it so so that it doesn't interfere with your grip.
Unless you have a bike that can pull a wheelie or smoke the tires I don't see how you can get into trouble with it. I tried to make it fail and I couldn't. It gets thumbs up from me. I could really see where it would make a difference on a long trip and it really made a difference on keeping speed stable, which really surprised me. Good product.
