Not accurate at speeds over 30 miles per hour. Between 30-40 mph it’s about 2 mph fast and it gets worse from there. At 70 mph it says I’m doing 75 mph. There is some lag but it’s not terrible. I also noticed it quickly loses GPS signal under overpasses.

After setting it properly, we suction cup'd it to the instrument cluster. This was a bad idea. It left a residue or burrowed into the plastic. It would be fine on glass or just laying on the dash reflecting off the window.I read that most people were saying it's off by a few MPH. You have to set it with a GPS on your phone. Search the app store.

I had a little bit different need from this device.The clock on my car radio is fast, adds about 10 minutes/month. The cheap stick-on battery clocks are also inaccurate. So I bought this with the intent to use it strictly as a clock in my car.For this use, it works. Others complained about slow locking time, but for me it takes 10 seconds after I turn the car on before the time is locked in, no problem. I also like the auto-dim feature.I took away a star for 2 reasons:1) The clock is always in 12-hour mode (good), but at 12AM or 12PM it shows "00" for the hours. The image included with this review was taken at 12:21PM and you can see it shows "0:21" - strange. I can't see how this "feature" would make sense - only in 24-hour mode (if there was one) should I see "00" for the hour.2) The device doesn't have any settings for whether to include the effects of DST. When DST changed, I had to manually switch the offset myself.But neither of these issues is a deal breaker, and overall I am satisfied.

Gives me a semi accurate speedo for my 2000 Jeep. I changed to a newer transfer case that isn’t compatible with my speedo. It reads about 2mph slow but thats not an issue. Works great for small $$

** (edited below) This product is a waste of money. . . . Completely useless, when im traveling at 65mph it says I'm going 73-75. The only time the speed is correct is when it's at 0. . . . Going in the TRASH***EDIT. . . . . . a few days after I posted this review I got a message from the seller. . . The seller apologized and gave me information and directions to get into the speed adjustment settings and how to dial it in. I adjusted it to the recommend settings they provided. I haven't got a chance to test it out as it is late in the evening. I wanted to post this update as soon as possible, I will also update this review after I use it tomorrow on how it performs!

Unable to connect to GPS until after 10-15 minutes in open area, which is very frustrating.The reading keeps fluctuating, always higher and lower than it shd be. I already used Garmin GPS, car speedometer and Waze for comparison. It is not smooth, can decend from 38 to 16 suddenly for example. Not reliable. (Even the Garmin GPS is smoother in increasing/decreasing the number, but it is just a bit slow. Waze's number is better but looks small in my tablet.)I returned back to Amazon at the end.
