I would go with less than 1 star on this company. I completely agree with all the reviews below! I had this installed for less than a week before I removed and replaced with a different provider. Prior to installation, I was lied to over the phone about how the device works, the size of it & cost. This device is absolutely awful to use when driving & it's unbelievable that DMV's would even allow it. We can't text, or use a phone in most states while driving, but this is allowed. Unbelievable! They will take as much money as possible too, absolutely go with a different supplier!!!
