big dissapointment
Bought this at the local shop on the recommendation of 2 people there. The first one I had to bring back because it did nothing, they exchanged it and against my better judgment after reading all the bad amazon reviews, I stuck with it. I was quickly disappointed in its performance but waited too long to return it so I am stuck with it. I have a VERY hard time hooking this gauge up to a presta valve without dumping loads of air from the tire. I have resorted at times to using a shraeder adapter which this gauge works more easily with, but is obviously very inconvenient and ridiculous to need to do. If I ever can get this thing to work without dumping half the pressure THEN the stupid slow response/startup time, and need to reset for a second reading are absolutely infuriating. DO NOT BUY THIS GAUGE!If you still think it looks good insist to try it at the store or make sure you can return it if you are with the majority that regret buying this.
