For the price completely ok! Then why but only 3 stars? It's simple: when the first few times the shutter is very difficult. press after few times, much easier. My guess: at some point is the really "wear out" completely. The subjects are of course only made cheap plastic, in which price can no longer be expected, but I'm satisfied. This is to leave the small alternative for it, if you just do not want to take his entire Portemonai, but only the most important and for this case was good enough. Therefore, when I have just no continuous use, how long would such a protrusion, maybe can not tell you for now and then: true value.
