I booked it for a 1200 mile dual sport ride and it failed at the first flat tire. The valve port on the end leaked quite a bit, but we managed on first use. Unfortunately, our trip was marred by apartments and the small compressor kept failing in the second apartment. same problem but this time it was terminal. I found another valve connector and now it works fine. I have a lot of experience with these small compressors in my line of work and none of them are totally reliable and the readings are never accurate. After I got back from my trip I contacted Bill at Stop N Go and he didn't hesitate to send me a replacement. I gave 4 stars because I still think the price is good and every manufacturer releases a lemon every now and then. But great support from the company!
