M1 Green Windshield Projection Heads Up Display, Digital GPS Speedometer with Speed, Travel Direction Function, ect. Suitable for All Vehicles (M1 Green)

Works great, the only problem is the piece of tape used to hold the unit to the dashboard down is not very good. A piece of Alien tape works a lot better.

Really cool little item.. plug and play .. A great gift for a new driver or any auto enthusiast..

Good and viewable, synchronization from actual speedometer is effecient

Great product easy to install and read on windscreen

It works great, very accurate, updates at like 5hz, and includes a reflector made specifically for it. I put it right next to my VIN plate. Long enough included USB-A to mini-B cable to route from console, behind wheel, next to door, up around the base of the windshield with like 2’ to spare in a service loop.BUTThe controls and the USB mini-B socket are all on the side facing the windshield! Catastrophic layout because this is supposed to mirror the readout on your windshield glass! I could see mounting the power on that side to hide it, but the buttons too?!Also, make sure you have a spare USB port! (Thankfully my iottie charger holder came with a car lighter-USBmicroB cable with the perfect USB-A passthrough for it).It does work, but be prepared to not use the included double sided tape and instead replace it with some 3M dual-lock.I do like it though. Been thinking about making one with an arduino or something for years, was nice to find that one existed already. It’s also way better than anything I would’ve made.You can disable all other info but the speed via the poorly placed buttons if you are so inclined.If you’re a fan of the Entropism design aesthetic, this is for you. It’s not elegant, not even designed well, but it does the job and I’d rather have it than nothing. If you want a reflector HUD speedometer, this is a serviceable one.

I had two of this type units. Green works fine but cant see it. White one is good to see but it stopped working in a week or so

Even after reading the other reviews took the leap to try it. Item malfunctioned after 3 days.

seemed to work okay at night but overheated during day time driving when sun shines the dashboard. while it did work the display was good and the speed seemed to track my manual speedometer.

excellent son pour les sirènes mais le micro est en plastique de mauvaise qualité. On dirait un jouet pour enfant.

Kinda blurry on the windshield

Don’t waste your time and money. Takes forever to connect to gps signal. Sometimes doesn’t connect for hours

It's 10 kms off of actual speed doing

Not accurate above 60km/hr. The calibration is way off - pretty much useless.
