I drive a dump truck. I visit the landfills and construction sites every day. So I'm constantly struggling to keep my tires in good condition. I use my pressure gauge as much as a professional tire fitter in a workshop. This one just didn't hold up. It's cheaply made. After a few weeks of use, it no longer fitted the valve stem snugly and gave inaccurate readings. You should probably buy something better if you use your sensor frequently.
