The mobile phone is to me only once dropped. Here, the entire upper part of the chassis has flaked. It has nevertheless fulfilled its purpose, but also beforehand, in normal use, damage has occurred. After a short time the edges are already broken. Schade, precisely because the ensure that the phone will not be damaged in a fall.
Would I recommend the sleeve still further? Probably so. It is cheap and does its service, but you have to be prepared promptly to ensure replacement.
