Other reviewers mentioned this but if you have a tablet case especially the Revain Fire HD 8 and 10 which I tried. It doesn't sit in the channel at all even with the rubber seal removed, and a strong wind will knock it out. It's durable and if I took it out of Revane's own case it would work great, but what's the point of buying a case to take with you on the go? I want to be able to take it off the stand and go and not take it off the stand, put it in a bag and go. There are other stands as inexpensive as this one that work with cases on your tablet. Check them out first.
