Review on Nitrous Express 15940 Automatic Bottle by Louis Loebis

At constant 12-14 volts this can take anywhere from 10 minutes on a warm day to over half an hour on a cold day. I wrapped it tightly on the bottom of the bottle where the nitrous oxide is as a liquid in the bottle. Once the nitrous oxide has reached the temperature, it is excellent at maintaining it, it just sometimes takes a long time to reach it. I usually take the bottle out and carry it with me so I can heat it up with a little heater while checking the pressure, and then throw it in the car and turn on the bottle heater to keep it warm when I want to spray . . I would really like to heat up the bottle faster when it's cold. But so far I haven't found a better and safer alternative to this bottle warmer. I'm a fan of all Nitrous Express products and recommend checking them out if you're looking for something similar.
