    It's worth about ten cents!  DON'T BUY IT!
  

*by D***N on Reviewed in the United States on October 5, 2019*

It works well enough, but the battery is dead EVERY time I try to use it.  At first, I thought that it had perhaps rested on the button, turning it on while I wasn't using it.  Finally I tried storing it in a little hard plastic box.  Still, the battery goes dead in less than two weeks.  Pay a little more for a better tire gauge, and save big on batteries!
