P**S
This little tool saved me having to replace the Tire Pressure Sensor located inside the tire at the valve stem. Once the batteries got installed, this device worked like a charm, starting at the front left and working clockwise with each tire, following the instructions that came with the unit. The reason I bought it was because the hole-in-the-wall tire shop said the TPSensor inside one tire wasn't working and would need replacing. It did not, the shop manager was trying to scam me. I had a feeling when the dash computer tire pressure only had no register for all the tires. Will be avoiding their business now. Easy to use folks, just follow the simple instructions. YouTube also has references for "Tire relearning procedures".

Seems like a last minute idea for a scam. If it really did work. Which it didn’t, it would still appear like the buyer was taken advantage of. It came in a craft sized ziplock baggie with a generic label with the products name hand written on the label. No instructions, no indication of hours to use it. Honestly, if I hadn’t had some sort of idea from watching videos already, I would’ve never known how it works. Excuse me how it doesn’t. Don’t waste your time.

Worked great on our 2007 Range Rover HSE. After watching several YouTube videos, I started on the left front, moved to the right front, right rear, then finished with the left rear. That cleared my TPMS light. Best $13 dollars I’ve ever spent!

It works great but its too bad you need a 12v battery for it.
