I have had this KGO for a few weeks now and the thing works great for the most part, but bring the thing outside in the humid air and the dang rubber button starts to stick. It is really rather annoying and it happens to both of them. I emailed the store that sold it to me and his answer was, when it sticks turn the button. This may help the problem, but they will stick again a little later. I hate having to worry about if my button is going to stick on these things...
