Karley was very helpful setting my appointment and was friendly.

When I spoke with a rep. to schedule an installation appointment they told me the completely wrong price (it was WAY more when I got there). I'm already upset to be in this situation, I don't appreciate being lied to and tricked out of more money.

If you want a trust worthy company to work with this is it. Too many horror shows through other device providers. Also Clay Dooley auto was excellent.

She was very professional and helpful. Was able to call the local store and set me up with a time that worked perfect with my schedule! Explained all of the charges clearly so I didn't even have any questions at the end. I would highly recommend this company so far!
