Leave it to Mr. Negative Maxtog.... after researching the system, my concerns with the FOBO 2 are as follows:
1) It looks like it might be enough weight that it might require rebalancing the tires with it attached. Claim is 7.6 grams or something (which is pretty freaking light). But that doesn't include the weight of the T valve, which probably weighs much, much more than the sensor...
2) I have had mixed results with bluetooth auto-pairing. On some devices it works well and I never have to think about it. On others, I have to manually connect them every time. If it were the latter, that would be very annoying. If you have to "connect" and then find and launch an app, then it is losing some of its advantage over just manually checking pressures.
3) It doesn't look like it will support Android Auto, which is the app that (I assume) most everyone would use on the motorcycle. So I assume checking pressure will require doing it before launching Auto, which is annoying and far less useful, since there would be no continuous, on screen (small) display somewhere. And if in Auto, I am not sure if an alert would come through (I suspect it would, though). This is a major disadvantage over the factory system, which can show pressures while riding, instantly.
4) Some users complain it requires Location services/permissions "on", which should not be required and is concerning. It is a battery-drainer and major privacy concern.
5) It is using Bluetooth 5. This is good from a range and power standpoint, but I am not sure if it will or will not work with Bluetooth 4 phones (my phone, for example, is a Moto G5 Plus, which doesn't have BT 5).
6) It appears to use cloud data and login credentials. This, for many, is a no-no. It means that if the company goes under or decided to not support your device anymore, you have a brick. It also means it consumes data on your plan, and introduces even more security and privacy concerns.
7) I also have to make a correction, there is no "T" valve assembly included. Without it, the sensors have to be removed, every time, to inflate the tire or manually check pressures. And since there is a physical security feature, not having a "T" would make it a royal pain to fill the tires. (I am correcting previous posting). The "T" is available as a separate accessory for $12 each for a screw-on type. But when you do use a screw-on "T", you lose the physical security features, making it much more theftable.
