Alright I'm a little upset with this... I've had the VTR About a week now and really like it with everything except my Fuzion Poison Apple, and KrankBerry. Right before I bought the vtr I bout a new Pyrex tank for those two juices. It doesn't fit the VTR so I have to use the extension piece. With both juices using the extension I get this bad burntish taste. At almost any watt/volt it's like that, except really low where I'm not getting any hit. Anybody else had any issues like this? Any idea what it could be?
