A mate of mine bought a Joe blow of some variety and I kid you not 85psi was the most it could get into his tires.Sounds like I got a duffer then, guess which retailer it came from who insisted there was nothing wrong with it when I tried to take it backone ray of sunshine, I don think it cost me as much as £27
FWIW I've had a JOE BLOW MAX II for a few years now and it's simply superb.
Easy to use and inflates easily to my required 120psi![]()
