Lensmate thumbrest vs thumbs up for X-Pro1

Have thumbs up and it's great. Have Lensmateon x100 and it's great too. Solved accidental exposure comp changes,. And accidental button pushes on x pro.

Got the thumbs up as soon as it came out because I knew it would make things better based on x100 experience. I bet Lensmate will be fine and it's much cheaper.

Wouldn't be without one or the other on either camera. Makes grip much more stable and secure.
