I have the Innocase, but the tabs have been breaking little by little, starting within the first month. I'm down to one for the back plate and I keep it mostly for grip with some double sided tape.

I looked at the Mobi ones and they are significantly cheaper, but the reviews I've read don't tell me much. I have read the Pre-Central one and the user reviews as well as the forum.

Can someone that has used both compare them?

Thanks.
