I am very pleased with this key that works very well and is very pretty. I can not judge all his duties, because I'm not used it the included functions (small program within which I have not at all taken into account. I just ignored these files) but for use I in fact, it is fine. In fact, I use it to record my TV via TNT and it works very well. Besides, a little more compared to the key which I used before and is completely lighted and flashing, which was unpleasant especially at night, it has a very small discrete diode. Concerning the strength of the plastic and holding the cap, I can not say because I few moves (the decoder to the computer). But if I had to spend my time to remove and replace the cap, I am afraid that after a while it takes really, because he does not resist greatly. But hey, it does not always have to rely on appearances, so I can not judge.
