Well I have to admit customer service before the sale was excellent and was still good the first go round. The second and third however sucked. First one was totally inop., they "repaired" it. Put it in, went bright and dim at it's own free will. Now I don't mean to be insulting, but I know what I'm doing when it comes to electronics, and at this point the tech on the phone was condescending as all hell and accused me of hooking it up wrong and frying it. I told him they'd get the gauge and I wanted a new one or a total refund. After quite a bit of heckling and me explaining how ridiculous it was for someone to have this much trouble with a brand new gauge he agreed to send me another. Got a new gauge, it's 5-10 degrees off one way or the other, no matter the mounting location of the sender.
Honestly, I wouldn't do business there again.
