DO NOT BUY! Update II: 4 months later. UNUSED I keep getting error E01, as you can see it reads 324psi. attached to the valve. For this reason, it is very difficult to inflate a tire and the pressure is never correct due to incorrect readings. Buy if you want a fancy paperweight. I've used it a few times on my road bike up to 6.7 bar, the gauge difference is 0.2 bar (3psi). The quality looks ok, the presta adapter pops out of the o-ring every time it is removed.
