Protect your phone, it's important ... And if it costs only 3.89 it is not very expensive! Indeed, for this price, this shell prevents scratching the back of the Xperia Z1 Compact which has the particularity to take very fast micro-scratches. I do not know if it protects lot of shocked because I have not yet had the opportunity to "mistreat" my phone ... I never served me the stylus supplied with since I ordered this item but I am convinced by the 3 protective films that are of good quality. The only downside of this hull which caused it to lose a star is that it does not allow access to dock for those who have a (you can view the pictures I posted), you must so every time remove and recover.
In short: An efficient hull against minor scratches and good quality protective films. Only drawback, it restricts access to the dock.
