I got my 4 ccps in the summer of 2013 & I used them for the 1st time this December & they went through rain, got buried in snow despite being 14 inches off the ground, then after the snow they were in freezing rain. No moisture was inside the controller. I can't say about the one ccp controller that was 18 ft off the ground. I will find out when it warms up. I ordered 2 more. The only thing I had go wrong was some annoying pixels that stayed on white all the time, even after the controllers were reset. They are being replaced & should be here tomorrow I would guess.
