Nancy Gravely reviewed Bezl for the MacObserver and comes to the following conclusion
The Minimalist for iPhone 5/5s from Bezl is one of the more unusual protection offerings currently on the market. It’s not a case, yet it provides 360 degree coverage.
Pros: Provides 360 degree protection for iPhone 5/5s through the use of four, hard plastic corners that prevent the front, back, and sides from landing on hard surfaces when dropped. Design allows full access to all ports and buttons and allows the phone case design and color to be seen.
Cons: Once removed, cannot be reattached. Product doesn't work well with tempered glass screen protectors.
