KAOLALI Universal Auto Speedometer KMH/MPH Mirror G3 GPS HUD Head-up display Car Speed Projector Universal for All Cars

This arrived as promised next day, I had read many reviews and looked at many options. I have to say I'm very pleased with it. Set up was easy. Long press on data wheel at side puts you into the menu, moving wheel left or right takes you through menu options, once you get to chosen part like mph press wheel in again and toggle wheel for desired setting (mph kph are just 0 and 1 once set long press data wheel and it's done. Legibility is very good. It's really quite small too,very slim, much better than expected. I'm very impressed. Only thing I would like is it to log miles permanently. When you switch off car, mileometer resets itself

See above..This unit is available under different trade names at vastly different prices. The units do function well. Check all alternatives,.

Had unit since August had no issues speedometer very accurate last few days though the display has started to break up making it difficult to read not sure if it's a specific fault to my unit or an issue with others

once calibrated and set to KM works as it should, takes a little while maybe > 1/2 min to "log on" to a satellite, I would think someone buying this item wouldn't mind, my TomTom takes longer to connect to a satellite.

Product is good quality but the the sticky pads came with it was to small and didn’t hold it properly for me. I have a sticky phone dash mat.

I absolutely love it. My only downside is about the fact that it doesn't dim low enough. I can live with that. It's marvelous. Thank you guys

Easy to set up. Nice looking device and not too big a cumbersome.

Easy fit and set up
