I wanted to wait until I wrote a review to make sure they could handle what I was trying to put them through. I have traveled to 24 US states in the last 5 months. In addition to the intense heat on the roads, I drove through snow, ice and frost. I was comforted to see them acting as the sole driver with the cat as a partner. I installed the front two myself, but because my dual tires were misaligned I had to wait for a tire shop to install the rest. I left the installation papers in Montana so I just let them do their thing. I didn't realize the setup instructions/details were on this page. The only time a sensor failed was during a freeze in New Mexico. At first I was scared, and then I realized that the street temperature was freezing. Soon after, the streets were warming up and voila! it happened earlier. It's not the product's fault, it's my fault for not setting it up originally. I will definitely (if and when needed) buy them again with confidence. I'm still 3 months away and looking forward to getting it set up properly. If you have an RV/RV you will not regret buying these for peace of mind.
