Review on Enhance TPMS Monitoring with 2-Pack Brass 🔧 Transmitters for TireMinder - TMG400C, TM66, and A1A Compatible by Donald Vargas

I ordered a full kit for my camper van but two were missing for the inner wheels. The master kit works great and is a great way to check and monitor tire pressure. These two additional transmitters continue to lose signal. The valve protrudes towards the outer wheels so there is clearly no interference. I can't figure out why they fail after a few hours of driving. With the other four working fine I still think this is a good security product, especially if you have a large RV.
