I bought a set of FOBO on Amazon for my 2018 F3L. I didn't like it for several reasons:

1. I knew fitment on fronts was problematic but I was ready to work with extensions and new valves at next tire change

2. Fitment on rear was ok.

3. For these things to be useful, you need a t-valve. Otherwise, you need to remove the unit when you need to inflate. That means having the little wrench with you all the time and fiddling with it until you eventually break the stem! Toying with the fronts wouldn't be too bad but the rear is royally annoying. I prefer to just take my pressure every few days. On my other bike, I had TPMS and was taking it every ride just the same.

4. I didn't like at all having to supply an email address to use the app

5. I didn't like having to read a 12-page privacy policy to install a gadget

6. I didn't like having to allow the app access to location services

This is just a little gadget, I don't get why it has to be so intrusive.

I am returning it to Amazon tomorrow.

Good idea, bad implementation.
