So I got a dozen or so lights and set one aside to play around with, and I've been playing with it constantly daily for a few weeks now and the button is already starting to fail. It works but sometimes instead of one click it does two, three or even four clicks in one press skipping modes. I've tested all my other lights and none have problems, neither did this one at first, but it seems constant clicking can wear these buttons out quite quickly. They sure do feel nice to press, but I think the buttons on the eLites definitely have more durability and last longer. Just a word of caution for people who only have 10 lights, try and go easy on them if you're wanting to switch modes a lot during shows, because constant clicking seems to wear them out.
