This is the one I have and I have not been impressed. The readers are not consistent. I set the pressure to 90 using a gage and they vary 5 psi either way. I was hoping to use this to check tire pressure but because they are off I still have to manually check. They also randomly disconnect. Sometimes when the toad is not connected it takes the tireminder up to 50 miles to figure out it’s not there. Then it’s not all four tires. I use it but typically just clear the message and keep on rolling. My last 500 mile trip I had three readers randomly disconnect. Definitely not worth the money.
