I've been using them for almost 6 months now and they work fine. They stay in place and are fairly reliable. The only issue I had was that the psi reading sometimes jumps 2 psi making the reading inaccurate, but only 2 psi and the temps jump a bit too. It's like reading in one block and looking it up to show it leads to another block instead of actually posting the result. Although for the price it's a trifle. This kit has already paid for itself I had a leaky rod that only spilled while riding and the alarm warned me straight away which I'm very happy about. Thanks very much!
