I also use a reptifog fogger, it is a zoomed. I had aproblem getting my humidity over 40. now it pretty much hovers between 50 and 65 and my little guy just shed and it was 2 large pieces, but it was complete. i got mine at petco, because of their no questions asked return policy. Even if you buy it at their online store, you can bring it back to any local store if their is a problem with it. My guy loves it and except for the 2 or 3 days after he eats he still uses his cool hide. I have it on a timer and it goes on every 3 hours.
