Pro: - after two months still dimensionally stable and encloses the mobile phone firmly (accurately) - The protection is effective. Phone twice popped on a tiled floor from from about 1.50 m. Everything absolutely harmless survived - Price is absolutely fine Cons: - Unfortunately, not blue as strong as in the photo. Rather pale blue with very slight slope to a mint green. - Back is not clear / transparent, but has a "milk glass effect" If the shell still buy again.
