Cheap plastic to expensive prices.

Really I do not know what you needed this "housing. It protects neither the lens nor the sides of the camera perfectly. Well you can the Camera through the housing on the side but the mount was also the only justification for the purchase.

Who the case only as a protective buys to want to film with no underwater housing in prime Quallität may also save the same.
Therefore it is extremely expensive for this cheap plastic. When the thread on side or bottom mount one should tread carefully otherwise it breaks faster than you "SonysPreispolitikIstFürDenAr ...." can say.
