Drying Out Issues
"Just got the system, and excited to try it. However, I tested it and found out the narrow top and sticky plastic on the inside means it virtually will NEVER dry out. You can't blow the sides apart on the inside because they collapse back in once you stop. Maybe there is a workaround, but the help center keeps telling me to do things like put a paper towel inside, which wouldn't come out if I did - - unless I rinsed it out, leaving it wetter than I had it before the paper towel went in."
