This worked really well until I was able to get the car's cluster panel repaired. It was very accurate for something so inexpensive.

There's a negligible delay in displaying the accurate speed. The unit has great display brightness and size. Works great if your vehicle's speedometer in the dash has stopped working.

This Speedometer helps me out in many ways. It is very easy to use ( plug it in and it works ). It runs off of USB power (5 volts) so it can run off of a cigarette lighter or a small power bank. On a power bank the power draw is very low. I've used it in my car as well as my E-bikes. One example is that I used it on a 5000 ma Power bank and it lasted a long time ( many E-bike rides). It's very bright so in bright sunlight conditions it is easy to see. It comes up in about 25 seconds. There was a long cord that has been helpful in many situations.

I read the reviews before deciding on buying this. Unfortunately, it didn’t work. It turned on just fine. No problem there, but when the car sped up, it remains at 0 🤦♀️ didn’t even go up to 1. It was a waste of money.

I have only had this for a few days, but it works well. Once plugged in, it takes a minute or two to find the GPS signal and then display the speed. While driving, the speed is pretty accurate when compared to the car's speedometer. The display is clear and easy to see in sunlight. I plug it in to a USB port connected to the car stereo, so when the car turns off, the device turns off too. Since it uses GPS, it needs to maintain its signal which it does while on the highway/roads etc., but it can lose its signal when you enter a multi-level parking garage/tunnel, etc. If you just need a speedometer only and no other readings, this is a good way to go.

Bought this GPS speedometer for my car because my new transmission cant be programmed to measure speed correctly. It measures 15 MPH to slow. Been using my phone app with app to measure GPS speed. This unit I bought from Lyiiiuan is easy to install, got a good display BUT is displaying 5 MPS to fast than actual speed and no way to adjust. I put it side by side my phone app and phone app was running correct speed. I changed to my pick up truck and tested phone GPS speed and it was exactly on the money. This Lyiiiuan unit displays your speed 5 MPH faster than you going. I will have to buy a different model next time.
