Bests & Worsts Reviews from Amazon

The problem with this is moisture. I have purchased two of them and after a couple of months, moisture from breathing into it and the heat, just sits in the tubes and ruins the retainers. When you go to extend it, the clips from inside break and render the entire unit useless. Perhaps if it was not in a sealed tube or if there was one of those oxygen absorbers in the tube? I dont know, but what I do know is I am not buying anymore as I have reached out to the company twice and obtained "zero" response back.
