Got my cheap plastic ones in the mail a year ago. Put them in with my bike and ball valve cap bin. If you check your tire pressure and not rely on the tpm you shouldnt have a problem. Two winters in extreme salty conditions and all AOK. Its just one of those damn things I have to pay for and I dont need. Doesnt anyone look at their tires anymore to see if you have a slow leak or flat. It cost more period! I'll take heated mirrors over the tpm on the RTS anyday,but then again who uses their mirrors?
