This tracker is excellent! I can see my teen driver's speed and location at all times! It definitely serves its purpose! The alerts provide speeding, rapid acceleration, harsh braking, and idling notifications. I can even tell when he is approaching stop lights based off the speed and refresh rate and I can tell where he is parked! Yes, all of this information is very useful to a worried parent! The Route Replay on the website can be tough to read when my teen driver has been multiple places in one day, but it still tells me all of the locations where he has been; just takes a little figuring out (better on the computer than the app). I can even tell when he goes through a drive-thru at a restaurant! There are a couple of issues on the MotoSafety website that I would love to see fixed. On the speeding alert, you can click on the alert to see the address where the alert occurred, however, the map does not show satellite and you cannot zoom into the address on the map where the speeding occurred. I would like to be able to show my teen driver EXACTLY the place where the speeding occurred. They do show you on the map where it occurred, but it's hard to pinpoint the exact location without being able to zoom in. My second issue is that I wish it would refresh just a little quicker. I have a tendency to start worrying when I see that my teen driver has been stopped in the middle of the road, but hasn't actually been stopped that long at all. Great product and highly recommended to parents of new drivers.
