I'm not sure where to put this so I figured I would throw it in the general section. I don't think I've read a bad review about avid vaper but another positive review never hurts. I bought their Amp tank about 4 months ago and made the mistake of carrying it around with me and went through 2 glass tanks and finally I dropped it on concrete and broke the connection. I contacted avid and they told me to send it in. They were fast with replies and only charged me $10 to fix the connection. I just received it back from them better than new. I'm extremely impressed with their customer service and just wanted to let you guys know about my experience.
