Nitrile rubber can tolerate short term dry running of the sealing lip. The operating temperature range without failure of nitrile rubber is 40 to +100 C. This also offers a special nitrile rubber compound with a temperature range between 55 and +110 C. Please click here for a full in depth look at the range of seals

Metal tab blocks magnetic charging
The set screws are too small and they do not have an adapter that fits the magnet charging rings on the newer phones

My favorite BMW car mount.
This is my favorite mount for BMWs. I have them on two cars (X4M and a 328), but I always modify the mount and install a metal ball (purchased here on Amazon) so I can mount an ESR Wireless charger. This combo is the best charging mount and system I have ever tried

sturdy mount nice fit
fit nicely and magnet is strong using the included metal disc to put inside phone case. was missing instructions but figured it out. you have to screw in the small set screws until it is snug. using a longer hex key made it easier.

Fits like a Glove!
Be patient screwing the 4 screws lol, but other than that. It feels heavy duty and fit like a glove. I LOVE it!!
