I know people have discussed this equipment before but I figured I would throw my experience in. I bought the set in December as a Christmas gift for my mom. Decided to upgrade her tank to a high tech tank. 15 gallon column. When it worked everything was great. 4 months later I have gone through 4 regulators and 6 canisters of co2. Things will run fine for a while and then one day all of the co2 will be gone. I've had a leak on the bubble counter as well, and on the first regulator had two canisters explode freezing cold gas as we screwed them in due to a thread issue. Now I am waiting to hear back from Hagen yet again. The only positive I have is Hagen has been good about replacing the equipment although slow to respond online. Either way I am really disappointed in the massive headache this has been. Anyone had good experience with this system?
