quit working in 15 minutes
on April 19, 2012
Installed this voltage monitor. It worked ok for 15 minutes, and then the numbers stopped lighting up. The "Stinger" logo still lights up. I e-mailed the company 3 times, but no response. I now know that "Stinger" products are junk, a waste of $$$, and that the company does not care enough to even answer an e-mail.
