Got this for a friend's bike after he had constant low tire pressure problems. A friend of mine installed these devices on his bike after months of having his tires blow out (or at least accidentally lose air). He asked if I could get him something similar and I was able to get him. He said the setup wasn't that bad (like any TPMS system, it's not fun), but it had a consistent signal despite the speed. Temperature or other conditions in recent months. Sometimes it takes a little twist to get the pressure accurate, but after that it works fine. All in all, my boyfriend is happy and so am I.
