so flipping through my GMhightech i just got and was looking at the"new products" section and notice zex has a new gage and it tells/measures how much nitrous is left in the bottle..now i know harris sold one lie it and daves sold a really nice one from trick performance(v and p series gage) but they are no longer made..so is zex the only one left..what are your thoughts on these gages? exactly how do the work
