What I like about this valve stem installer, if you can call it that, is that the part that screws into the tire valve is captive. It won't fall out or get lost along the way, leaving you frustrated at not being able to stick sausage roll fingers in the 2.72-21 front tire to pull out the new tube valve. This tool is of the highest quality and a must have. there is when you want to patch up your backcountry pipe or install a new one because you ripped the old one. I recommend this pipe to others like Tusk. For added security at the most important part, the part that takes the valve out of the stem and screws it in to pull the stem out through the hole in the rim.
