Auto Car HUD Head Up Display KMH & MPH Digital GPS Smart Speedometer with OverSpeed Alarm Fatigue Driving Warning, Navigation Compass, 2.2'' LCD Screen, USB Plug & Play, for All Vehicle (‎G13)

Got it unsure of whether it'd be good but I'm quite surprised of how good it is for the price. Its great quality and sticking it to the dash is easy and secure. The display is decent quality, wish there were more options to customize it but it's very clear and less distracting than looking down on my dash. The auto brightness is really useful for day and night, I wish the display updated faster but it's still pretty responsive. I've not used the GPS function but the OBD view is very informative. The speed is off by a bit but is adjustable enough to be accurate to the speedometer dial on the car.

This is a fantastic product that is highly accurate when set up correctly. For those that state it is inaccurate obviously haven't / couldn't / can't be bothered to read the instructions. Don't listen to the negative reviews, I rode all around Europe with this on my bike as my speedo had broken and it never let me down once. Well that is entirely true, it couldn't read the satellites whilst travelling through the Mont Blanc tunnel but then what device could. Okay, some smart alec is going to come along and tell me that when they were in the SAS they had something that could. Yawwwn.

Good little speedometer for Driving Instructors - easy to fit to the windscreen using the included suction cup mount (the supplied dashboard mount and pad however were totally useless on the dash of my MK8 Golf). The accuracy is pretty good for the price although as it’s satellite based there is around a 1-2 second lag on the readout. But, it’s very easy to read and small enough to be discreet.

Used this today and it worked for the 2 hour trip I was doing but when I got there it went off and now will not turn on. On inspecting the micro usb port is loose. Not good at all

Chose this Speedo to supplement the analog speedometer in my car, which is small and not easy to read accurately, to prevent myself from being caught speeding accidentally. It is compact enough not to obstruct the windscreen with a good sized and clear display. Very easy to install with a suction holder on the windscreen and plugs into a USB port. The displayed speed reading is surprisingly close to that of the car‘s own speedo - even better than the Speedo app on my phone.

Easy to fit and easy to use. Plug-in and off you go

Delivered promptly. Yes, written instructions are very small, solution? take a photo on your phone and enlarge it and stop being picky. Worked straight out the box, top tip, plug it in at your desk or mobile charger and set it up in the comfort of your own home rather that the car. Needed it for a trip to France in an old Freeland2 where the KPH symbols are virtually invisible. The 2 inch by 2 inch screen is very visible, sits neatly on top of the dashboard. Needed to calibrate the speedo as it was consistently 5-7KPH higher than car speedo. 30 second job. Great gadget at a price and will help keep me legal in France. Would highly recomend

It’s been almost a year since i am using for my car. Works perfectly fine, very accurate and good quality product. Attached to wind screen at eye level.I’d definitely recommend!
