Although a great price they are useless if they don't fit in the car, although the listing says otherwise. After I installed them on my 2008 Dodge Magnum, no mechanic could get them to properly pair with my car. Pressure readings from each sensor (yes, all 4) show over 240psi each. This puts out an error code from my car's computer, causing the TPMS light to illuminate on my dash. NO SUPPORT from the company. Voice messages left by US dealers believed to be providing tech support go unanswered. No one answers tech support calls.
