Works Perfectly!
This product does everything it says. It does take a while for it to find a signal, but a solid minute or 2 and it has it down. Tracks time, provides odometer, speedometer, and the trip. Really easy set up, only issue I have is the adhesive isn’t strong. Took me all of the gel adhesives provided until the very last one to get it to stick. (Could also be due to colder temps). My only recommendation especially if you have an older car that vibrates a lot like mine is to get your own stronger adhesive.

Worthless
Total wast of money . During an hour drive it might display 5 minutes .

surprising how well this works
I used this in my RV since the speedo is hard to read. This seems to be accurate, maybe 1 high at 60 (and it can be adjusted according to the instructions, though I haven’t needed to). Very visible and adjusts brightness really well at night. Great device for the money

Easy to read and install
I live in a golf cart community in a state where the speed limit for golf carts is 20 mph. Since golf carts don’t come automatically with speedometers, I’d had a guy install one but it was really a bicycle speedometer that worked with how many time a given tire revolved. I never thought it was terribly accurate and not that easy to read. When it died, I got the OinDoDi Digital GPS Speedometer and installed it (basically, using a sticky base attached to the windshield and a long supplied cable to get to a USB port on my cart). It does take a few seconds to lock onto the GPS satellite network, but after that I am 100% confident in its accuracy and it’s really legible and easy to read even in bright Florida sunlight. It does have a few extra bits of data displayed that I don’t pay any attention to. I dock it a point only because I can’t turn those off. You might actually like that information. Recommended.
