Anyone have any experience with these?

they were already installed in a set of tires I just bought and mounted. I have driven about 30miles on them and got the tire light on my dash and all 4 psi read outs went blank.

Sounds like the wrong sensors .. were they 315mhz ? not sure what you mean by electric either ?

i have no idea what freq they are as the tires were ready to mount when I got them.

Electric is part art of the company's name.

also, the light went out and the monitors are working again! Weird stuff but, I still intend to buy a programmer for them.

thanks for your reply.
