I picked up the camera armor for my Canon XTI, and have used it a few times now.
Overall, I like the protection it offers, but there are a couple things about it that bug me.
1. The automatic display off sensor thinks the camera is at eye level ,so the lcd display stays off.
2. Lens changing is more work, especially if the lens is slightly larger in diameter. The rubber gets in the way of the mount and needs to be worked while mounting lens.
3. the on-off switch and exposure mode dial are more difficult to access.
Again, the above problems are minor compared to the benefits of added camera protection. I am hard on equipment and I know this protection will come in handy in the future, so for me it's worth it.
