I didn't search online before shipping them in. Wish I had. A lot of bad reviews. Place is called NEAT Computers. I sent mine in to be tested and now I'm thinking about contacting them and asking for them to just send them back and charge me a handling fee and return shipping. I'd hate to loose mine and end up with something that not only didn't work, but wasn't even for the right vehicle. Sucks that they just shipped this morning and I looked the place up this afternoon.
