I bought the xhale 02 from 711, it stopped working after a couple days. I'm guessing it's because I overheated it (puffed too often without letting it rest) or I rinsed something that shouldn't have been rinsed. I'm going to try buying one again and I wanted to know what I should do this time, in terms of how much to puff and how to keep it working at peak.
Thank you
