First time I used it the rubber gasket blew out. Pushed it back in and it blew out again. Pushed it back in and was able to get tire inflated but had to go very slow but the gasket was damaged so it leaked could not get proper psi had to cut ride short. Tossed it in the garbage!
I just went to a tubeless tire and the speed of this tool is necessary. Love how small it is and how well build it is to handle the threaded CO2 cartridges!! Can't believe I didn't go to this sooner. Doesn't matter is you have tubes or not.
