Review on ITM Set of 4 TPMS 433mhz Tire Pressure Sensors for 2007-2009 BMW 3 Series Coupe Sedan 328i 335i E90 E92 - Effective Replacement Sensors by Rob Parsons

I read countless reviews online and was really concerned if they would work flawlessly on my 2009 328i E92 xDrive. However, it was so much cheaper than the recommended genuine parts (which averaged $70 each, down from just $280) that I thought it was worth a try. I needed a new TPMS because I got new wheels/tires and one wheel had a crack (constant air loss). While working fine (for a few days), the TPM error signal is completely gone! I'll update this if that changes, but if it holds up (and is accurate, we'll see if it reports low air pressure correctly) that's an insane dollar savings on TPMS.
