Hey guys. So I have been vaping on a UDT-V16 for a while and I was wondering if anyone else has had a negative experience with the button making contact. Shortly after I bought it I noticed I kept having to increase how hard I was pressing the button for it to fire. I've gone to huge lengths to ensure its general capability. (taking apart the entire mod and insulator to mess with the metal tab that the button hits to complete the circuit) Every time I do this the button works PERFECTLY for around 48 hours and then it starts to veer back into the realm of "not wanting to fire unless 3,000,000 lbs of pressure is applied" mode. Wondering if I got a faulty unit or if this is a common issue with this device. Thanks for the help!
