Cool gadget with easy setup
Quality on the product is definitely lacking, but setup was quick and easy. I’ve noticed the device doesn’t accurately tell speed above ~60Mph (It will display around 3 mph higher than the car is actually going). The adhesive patch for attaching it to the car is very weak, I ended up replacing mine with a higher quality one. Good value for what you get.

Works well
The speedometer on my 05 Tahoe is broken so I bought this to use until I can get it fixed. It works great and as far as I can tell, it is accurate. It tells me the exact same speed as Google Maps. It also turns off when you shut the car off, which is nice

It gives wrong data
It can’t read the engine coolant temperature correctly. Very bad product. Not even as good as the OBD dashcams from a few years ago.The engine is not running and the temperature keeps changing

Small, Compact, Worth it
It definitely has that quality feel to it. I would say I wish the cable that is connected to the display was at a 90° angle. I did have to factory reset it because it would not show the RPM other than that it works as intended and is pretty accurate. (Size reference down below)

Simple plug and play setup. Easy to use.
This unit does what you think it does. Speed, distance and time. It does much more but for 99.9% of the users, it works very well. Simple plug and play install. The cable is plenty long enough to run it in between dash trim and to the connection under the dash. Unless you drill a hole specifically for the cable, you will be able to see some if not most of the cable. Small enough to be place in the center of the drivers-side dash without blocking the drivers view.I gave 5 stars but wish I could give 4.5 because the unit is bigger than it needs to be. The odd shape doesn’t fit easily around the dash. Flatter would seem to work better instead of the flat bottom triangle. The sticky mounting pad included is kinda worthless. It will require a much stronger adhesive so that the unit can tolerate vehicle vibrations and bumps over time.The readout is easy to see and read. There is an auto-dimmer and also a manual dimmer. Even on the lowest setting, it’s plenty bright in your peripheral vision at night.I recommend this unit for the simplicity of set up and use.
