## Customer Reviews

### ⭐⭐⭐⭐⭐ Inexpensive and useful
*by R***E on July 6, 2025*

This worked pretty well. I have a heads-up display on my car, so I wanted to get one for my daughter. Her speed control is not very good. She tends to drive too fast, then too slow -- not at a steady speed. I am hoping that the digital readout will make her more conscious of her speed. Since I started using a car with an integrated heads-up display, I've become much more conscious of my speed.It's easy to install. I would recommend getting a USB hub as it will use up one of the USB ports (nowadays, those are cheap and available).It only does speed measurement and it's as accurate as GPS can be, which is to say not as perfect as an integrated HUD. However, the device can be calibrated for accuracy (add or subtract a few mph, as needed). It also shows direction (North, East, South and West; when going in between, both lights are lit (e.g. both N and W when pointed northwest).The cord is unsightly, but if you saw my daughter's car, that would be the least unsightly thing you'd notice (think pizza boxes and water bottles).It was not obvious to me how to position it so that the display was perfectly straight up and down (if that matters to you) because her dashboard is curved. I found the best orientation and left it at that. It comes with a reflective rectangle, but making that match up to the display was not an obvious task and frankly the display is bright enough without it (although I have not observed it during night driving).This device is so cheap it's really a wonder why anyone would go without a heads-up display. Well, I think my fussy wife might object to the visible cord and even seeing the device on her dashboard. But for an after-market device, I find it perfectly suitable.

### ⭐⭐⭐⭐⭐ Great product!
*by H***P on July 17, 2025*

Great product. Very accurate!

### ⭐⭐⭐⭐ This has been every little boys dream for decades!
*by T***Y on October 27, 2024*

My car likes to tell me things, and when it does it replaces the digital speedometer with various symbols every fifteen seconds until I fix whatever it's complaining about.This HUD let's me project the speed straight onto the windshield, which is just awesome.A tip on placement. Look through the windshield like you would while you're driving, and find that spot. Then place the HUD projection a couple of inches below that. You don't want to put it in the center of your field of vision because it'll always be getting in the way.This thing is also packed with features, most of which I don't want. I don't want it to beep, ever. I don't want an over speed alarm. I also wish the display was a single color. The rainbow sherbet color scheme is ok, but I'd rather it just be green or red.Still, this thing is really cool.
