All four (4) sensors failed to register with the car's TPMS system. Vehicle stock 2010 R56 Hardtop Mini Cooper. Reinstalled several times, didn't help. I heard that around 2009 Mini changed the TPMS, either the frequency or something else. I'm not sure how to tell which versions of the cars they were; nobody seems to know until the current sensors are removed and tested. According to the description it should fit as an OEM - but it doesn't. The cost of removing the wheels and sending them back is more than credit for them, so 4 incompatible sensors are stuck.
