It leaks from sides and if you try to tighten valve to improve pressure it you will grind soft metal grooves away until lever spins freely. It would be better if groves that hold handle would be made from a bit harder metal. It is made up to a price. It is good for an emergency, but not for long. I just wanted to use up few remaining co2 bulbs that I still have then it is going to the bin. I use it for co2 for dispensing beer.
