I pre-ordered the first one and had a lot of problems with it constantly losing connection and not tracking trips. I checked the app a few times to find out that data was just not collected, and it was just cumbersome to get the device to reconnect, with having to turn off my engine and do a dance to get it to talk to my car, that it just became a pain and sat in my glove box for months.
Hope they've fixed these issues, but I'm skeptical about buying a 2nd gen after that experience.
