Took me a bit to figure out the instructions (3 settings) but it works great and my wife loves it.

I drive around 40000 miles a year, so most of my driving is at night, and this works for the most part, but it is very, very bright. I also noticed that the odometer is reading a little faster than normal.Maybe 1 or 2 miles per hour, which isn't a big deal.But overall not a bad product

I have bought and used a few different HUD’s and by far this is the best one yet. Bright enough to be seen in the day but brightness can be adjusted for night time driving. It may read a mph off but I’ve found that is usually caused by the tires on your car. If this heads up display ever stops working I will definitely purchase another one that is exactly like this. Can’t go wrong with buying it.

This is a review for: Heads up Display for Cars Windshield, Car HUD Display, Plug & Play USB, MPH/KMH Switch, Speed Calibration, Adjustable Brightness, Overspeed Alert, Large Font DisplayWorks pretty well. Display is easily visible day or night, but easier to see at night. The speed is accurate to about 1-2MPH, and it's possible to calibrate it to be even more precise, but the instructions to do so sounded like too much math, so I'm fine with it's being a couple miles off. It's close enough. The cord it came with was way too short to reach and of the cigarette lighter or USB outlets in my car, but I have a TON of extra USB A to USB C cords laying around my house, so it was easy enough to find one that's long enough. It's really hard to see when wearing polarized sunglasses. Very easy to set up, just plug in, place on your fasha and you're good to go. For under $20 I think this gadget is a great value and would be great for someone with analog-only gauge cluster or really anyone that wants to check their speed without taking their eyes off the road. I would definitely recommend it.

Yyy
