Query: read this before you buy

I bought this digital tire gauge a few month ago. It work really good until recently when i tried to use it. The screen would not turn on. After pressing the buttons a few times, some weird numbers started showing up on the screen C 1 and 1365 not sure what it was doing.. Anyways tried to put it to use again and the reading was totally off. Changed the battery and still same results.
