Very easy install, works well. Tested and is within a1-2 MPH. Lower which is good, keeps my daughter from speeding and keeps her eyes on the road. Great price.

I ordered this to see how accurate my car’s speedometer is. The device works perfectly. All it does is MPH, and that’s it. However, the price was way more than fair. The only downside of the device is that it must be plugged in via a USB cable. But the cable gets plugged in ON THE WRONG SIDE!!! To place the device in the window properly, the plugged-in USB cable faces the window or the front of the device rather than straight out the back. Making the cord snake around the device constantly pulls on it and tries to turn it. They provide double-sided tape to hold the device down if you want to stick tape on your dash.

Works good. Easy to see in day and dims for night. But it is 2 mph over the real speed. But I just subtract 2 when I see it.

So is working good, very easy to install, good design. No need to be calibrated, accurate reading.Update, it has been inside the car, having high temperature and still working good.

Very durable made solid. The display is bright, and the functionality is great as it reads speeds, accurately, and swiftly. It’s easy to install, as you just simply put the reflective sticker in the windshield and then line the device up with it, so the display shows in the reflection. The appearance isn’t jarring or anything like that and it’s easy to mount because it has a sticker a stick to your dash and it is two sided so it also sticks to the device.

Good product, nothing exceptional but work. Accurrancy 2 miles below real velocity. Good relation price- value.

This is a great heads up display for my 2008 Mazda 3 which has a speedometer which is difficult to read in daylight because of black numbers on a gray background. Be sure to test placement before sticking the display to the dash. I thought it would be great straight in front of me, but under some conditions the brightness can be distracting, so I put it near the glass at the center of the dash instead. The double sided sticky mount that was supplied did not work with my dash so I give it only 4 stars, but I found after trying several others that 3M-VHB-5932 1.1 mm double sided tape worked great. Some have said its speed ratings are inaccurate, but it works by GPS, so if its speed is different from your speedometer, its your speedometer that is wrong.

I don't usually leave reviews but this K1 unit really deserves a good one. No more eyes leaving the road to make sure my speed hasn't crept too high, particularly in the 20mph zones. It's accurate, very easy to install with a super-long USB cable, enough to route it unobtrusively and I don't need to stick the supplied reflector on the windscreen as the number is totally readable without it. I rarely drive at night so haven't experienced that as yet. This little thing has literally transformed my driving experience and I'm delighted with it, I just wish I'd learned about them before they were mentioned on a driver awareness course.

Don’t buy it. Waste of money and time. It’s super cheap stuff. Plus not real time speed meter. I wonder why Amazon has approved such vendor on board.

It's pretty useless and isn't customisable. The listing doesn't accurately describe the product.Waste of money.

Completely misleading , only tracks MPH as off by abit doesn’t track in KMPH which is what I need in my country
