I've crimped about 300 of these buttons for a number of Arduino projects over the past few months. In terms of quality, they are a bit rough (sometimes mutilated from the bag) but still work well, but for the price that's no problem at all. My only complaint is that they are too tight in the packaging, making them extremely difficult to remove later. However, if you swipe it open a little and drop WD-40 on the connector, the problem is solved.
