TOPEV Car HUD GPS Speedometer, Digital Speedometer Car MPH, LED Large Font Display, HD Display Meter 3 * 2 Inch Font Non-reflective，Speedometer for Cars Trucks SUVs Motorcycles (White)

Very useful & true to real time info

Very good in a real time sync…. Quick connection. Works perfectly

Disappointed. It takes a couple of seconds for it to display the correct speed whenever you speed up or slow down. Unless you are going at a constant speed it is useless. It's important to know the speed every single second to avoid triggering speeding fines. I've wasted my money.

It has a stall of a few seconds but it is pretty much accurate after that..

Use this in my Motorhome (Transit based) and works very well. Plugs nicely into dash usb points and sits in the corner of the windscreen to prevent reflection.So far my only suggestion is to make it light sensitive and dim down for night driving as its very bright and can glare. This then becomes a distraction especially when driving on unlit roads.Would pay slightly more for this feature..

I liked the idea of knowing what speed you are doing without taking your eyes off the road because the monitor is sited on top of the dashboard and within view of the road in front at all times no need to move your head

I've used it for about 2 months but unfortunately the the cable had loosened making it unable to use

Works very well and very accurate, easy to use and readable
