I still have 2 devices of the first generation that work 100% without any problems. I bought 2 second generation devices but only used one of them. so far. I've been using the second generation for the whole of last summer and it has worked fine, except that every week or so it has stopped responding and I had to unplug it and plug it back in to get it working properly again. However, I never had this problem with the first generation, not even in the same place with the same application.
