Your little comment of "Contrary to what our other customers say" is really telling of the problems with your product.
First off, there's LOTS of complaints here on this board alone, as well as all over reddit and other review websites. The XS GO is widely considered a "Ok first step but go buy a real one ASAP." vape in the eyes of the majority of people (IE: The ones you don't seem to listen to.).
Secondly, if your engineering team was so incompetent that they put plastic blocks in front of the airflow holes in a machine made to vape substances that can cause ANY sort of buildup, I don't really have any faith in them to improve.
Third, keep your mock pity. I've seen the way the Customer service treats people on here and I'm not buying the sweet talk. You'll be getting an email from me, alright.
