Review on 🚗 Enhance Driving Safety with VJOYCAR R1 HUD GPS Speedometer: Universal 3D Head Up Display for All Cars, Truck, and Vehicles by Gilbert Cokky

You know, with these products from little-known Chinese companies, it can sometimes be awkward to order. But this is a real winner. Very easy to set up - it's ready to go straight out of the box and the included high quality 3M branded stickers are great for applying. They stay in place but can be removed if necessary. The displayed speed adapts to your speed changes in near real time. It has a nice "offset" function. So if it keeps showing a certain (small) number of units (e.g. mph, km/h) above or below your true speed, you can tell it to show a certain number of miles per hour or km/h. h less or more than calculated. However, the displayed speed corresponds to the speed of my car. The instruction manual wasn't clearly written, as is the case with many of these products from obscure Chinese companies, but that was fine because it was very easy to set up and use. The display is perfectly bright day or night. And you don't have to stick reflective material on the windshield - I love how the display works. My wife and I are so pleased with it that we ordered another one. Fantastic work VJOYCAR!
