Query: the gauge is poorly made

I bought one of these for my grand prix,easy to put in but did not work.I called the sunpro helpline to firgure out what was wrong,they said it was a bad internal ground.So I sent it back and ask for anothor one.When I got it had the same problem, sent it back and got a refund this time.[By the way the problem ground makes the gauge read rich with car on or off nonstop]
