Unfortunately I have not been extensively tested, but before I got the product, I had bitched because the program was too long. Eigentlichj it's not so bad and not so long with the shipment. Approximately 2 weeks I got it already. One thing I have to mention that I have purchased the product for Xperia Z, but it does not fit in the description is. It adapts Xperia Z1 Compact on anyway. What about the charge I will report further, because I have too little experience with the product, but four stars can I forgive in advance.
