Review on 🔧 Ensun 13598771 TPMS Sensor 315 Mhz, Programmed Tire Pressure Monitoring System Sensor – Pack of 4 by Tommy Penn

Purchased for a 2009 Chevy Avalanche: Either they didn't work at all or the transmitters weren't strong enough to be recognized by my car's computer. Only 1 out of 4 was installed so it could have been a lemon. But I didn't want to try to install another one and risk one not working and have them charge me more for the installation. So I ended up buying one of these (Walmart) and they worked great. Here's an attempt to save money. On the plus side, Revain gave me my money back and I didn't have to return the product.
