FOBOBike works flawlessly. I've had mine for a lot of miles. Shows temp and pressure, alerts you with an audible signal if either gets outside parameters you set. Never failed. On the rare occasions that I need to replace a battery (I do it annually as a precaution) I can do it in 60 seconds, both wheels. To run any stem-mounted sensor, you need metal valve stems. So if you're going to replace your stems, don't just go metal, go with T-stems. About the same price. If I want to check or top off air (which I really don't have to do anymore, except once a year in the winter, but you never know), I can do so from the side, where it's convenient, and without removing the FOBO sensor. I have a garmin fancy schmancy gps that does everything, to include tpms. I'm not buying their caps, when fobo works flawlessly. With FOBO being my first TPMS, I am baffled at systems that require you to remove a tire to change a battery. I have a number of safety features on my bike, from SPOT, to admore light bar, to Realtime reflective bag decals. With the possible exception of the realtime reflectives, the FOBO is the most cost effective safety feature I've added to the bike. I don't keep it heads-up all the time. Usually I just set it and forget it and know if something happens I'll get a klaxon in my helmet. Good luck whatever you choose.
