Great design, terrible performance The design and concept are great, but the actual experience using the device as been a grade or two below mediocre. Not a single day without errors impairing its basic function ... wrong parking location (often half a mile away), missing trip data, frequent disconnect errors, etc. Customer service is responsive and even sent me a replacement device, but the problems persist. We live in a mid-size town with excellent cell coverage.

I have only had this unit a month now… I have only had this unit a month now and from day 1 to present time it is not working properly as I have to keep updating events and alerts. I am returning this item today purchased from Amazon and would not recommend this product to anyone. I want my refund now.

Don't buy this Inaccurate, oversensitive, and slow. The device doesn't notify the app until several minutes after a triggering event, which could be the difference between life and death in some situations. Also, the device gives hard acceleration and hard braking alerts way too often; I rode in the car with my son and the whole drive felt quite smooth and safe, but the app gave three notifications for acceleration and braking. Also, on this drive, my son never went over 50 miles per hour, yet the app said he went 60. If he wanted to, he could simply unplug the device and we would know nothing of his driving. Plus, one time, it gave an acceleration alert from 34-17 miles per hour. How do you accelerate from 34-17? I would never recommend this device to anybody.

It has worked great most of the time It has worked great most of the time. There have been approximately 3 times that we received an error message about the location of the car when our son was actively driving. Other than those few times it has been great and since installing on our son's car he knows we will know how he is driving so he is much more careful and gets fewer alerts than when we first installed it.

Not Impressed I bought this to track my classic car with a modern engine but thought I first test it in my 2015 Chevy Volt. I drive about nine miles to work each day, each way. Looking at my tracks I found them to be incomplete. Starting miles away from my house or office and ending before my final destination and multiple trips within one drive. Every day my tracks have different distances for the same drive.
