Essential piece of kit

2026-01-27    -derekb

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.

4.0 out of 5 stars Great little gadget for new drivers

The media could not be loaded. I’m a new driver and this HUD display has been really helpful. It was super easy to set up — just plug it in and it works right away. The numbers are big, bright, and easy to read, and the build quality feels solid for the price. The brightness adjusts automatically, and the speed reading is pretty accurate. It can be a bit hard to see in very bright sunlight, but overall it’s well-made, easy to use, and a great value for money.

5.0 out of 5 stars Little price to pay for High Tech quality once available to high end vehicles.

The media could not be loaded. Made a great addition to my 40 year old Honda civic. Functioned well with great gps accuracy and the usb plug and play makes installing the unit effortless. I router usb cable between windshield and dash. Turns on in 3 minutes with the car out in open for gps to function well with sleek streamlined design and excellent reflective quality on windshield. Illumination self adjusts from dusk to dawn brightness. Great price and quality. Highly recommend. Would purchase again.

5.0 out of 5 stars Straightforward and functional - love!

Really easy to set up and very functional! The numbers are easily readable in all light levels, and not too bright at night. I love the simple design and navigation, and I love that you can control whether the device makes noise or not.There is a setting that will make the device beep repeatedly if you hit or surpass a certain speed, and the default value is 75mph. This is a nuisance on road trips when on interstates that have speed limits of 80mph, so it was helpful to find out that I could edit the speed it checks for or even turn off checking for a certain speed. When you hit the designated speed, it will beep several times and then stop beeping, but the numbers will flash as long as you're at or over that speed. When you hit the speed again (either coming down or going up), it will beep several times again. This is nice as an audio indicator of your speed if you like that, and would be good for situations like a teen learning to drive.The default speed accuracy was off by about 2mph (over my actual speed), which you can easily adjust in a setting on the device to get a perfectly accurate speed reading.This connected to GPS very quickly and easily for me once I plugged it in. For reference, I live within city limits of a medium size city and within range of multiple cell towers. Connectivity and connection time can vary depending on your location. This doesn't connect if my car is in a structure like a parking garage, but will connect shortly after leaving the garage.Overall, this is a wonderful value. I'm very happy with this purchase! It would be nice if it was wireless and powered by solar (since it already sits on the dash), but I'm happy with it as-is.

Mph to kph

Can i even switch the mph to kph with this thing? I really like it but if its gonna say mph then i would still look on my dash for my actual speed

5.0 out of 5 stars A Surprisingly Awesome Upgrade for Any Car!

2026-01-19    -Shahid

I honestly didn’t expect much from a HUD at this price, but the KUOWEIHUD completely surprised me. Setup was literally plug-and-play—I plugged it into my car’s USB port and it turned on instantly. No apps, no complicated menus, nothing.The large digital display is super easy to read, even in bright sunlight, and the automatic brightness adjustment works perfectly. It brightens during the day and softens at night so it’s never distracting. I love that I can keep my eyes on the road instead of glancing down at my dashboard all the time.The GPS is very accurate and connects quickly thanks to the dual GPS+BDS chip. The speed updates smoothly with no lag, which gives me a lot more confidence when I’m driving in areas with strict speed limits.One of my favorite parts is that it works with any car—new, old, truck, motorcycle—doesn’t matter. It also turns on and off automatically with the car, so I don’t have to think about it.For the price, this is honestly one of the best little upgrades I’ve added to my car. If your speedometer is hard to see or you just want a safer, more modern driving experience, this HUD is totally worth it!

High quality product

Very quality product. It takes some time to initiate when you connect for the first time. But overall quality and working is excellent. I am very happy with the display. Very useful while driving on expressways where there is ceiling on the maximum speed allowed. The display is bright during daytime
