This inflator regulator is perfect for inflating balloons for my automotive shop's promotions. Through trial and error, i found that this product is easy to use and has a consistent flow of helium. The screw-on connector fits securely on my helium tank, and the adjustable pressure gauge ensures that I can inflate balloons to the desired size without popping them. The only downside is that it's only designed for helium and cannot handle other gases, but this is not a major issue for my needs. .
