I ordered the envelope - of course to protect my S4 - at the price and at the appearance of the product you would like to think that the product is really really good. The cover keys worked great, you could the unit seamlessly with most plugs Load (Samsung original plug went!). And most jack for the audio jack went. So all in all makes me happy the product.
Why now of a star? Now, the question is easy to answer. I, and probably many others realize certainly that this is a brand product. This putative brand product but broke without warning and without any external influence (I always carry the phone in my breast pocket). For the price it did not even four months! Sorry!
