Very good gauge! The only complaint is that he can be a bit temperamental when it comes to finding the best place for the valve seal, especially on those hard-to-reach motorcycle valves. *UPDATE* After years of use on various cars, bikes, bikes etc. I noticed that the reading on the sensor no longer matched my other AutoX sensors/gauges or the car's TPMS. I wrote Pit Posse about calibration, they said it is possible with disassembly but not recommended. Asked for proof of purchase, looks like it's still under warranty (just about) - and a replacement arrived in my mailbox! Fantastic customer service for a reliable product!
