I ordered this unit to go in my golf cart. The problem is that it only works while plugged in to a USB port . The description does not make clear the port is required ,so I am sure that there are other disappointed purchasers. Luckily, my cart has a charging port so I was able to install the unit. Unfortunately, trying set the unit up was anything but easy. Once I was able to get the unit to actually display my MPH it only worked until the power on the cart was turned off. The unit would need to be re set when the power was turned back on.I had high hopes for this product but would certainly not recommend it for easy use.

You just get the simple display and plugin for power. There is nothing else that comes with this to help mount it. Guess it is separate.

This is a great little GPS speedometer. It took a bit for it to grab the satellite connection, but once it did it was able to maintain accurate reporting of the speed down to a single mph. The build quality is meh, it's not the best, but seems sturdy enough.Great gift idea or stocking stuffer.

It stopped working. I’ve had in my truck for just over 2 months. And it already failed. Supposedly this product has a 2 year warranty. But there is no way to get in contact with customer support. Very disappointed. I’ll have to buy a different one next time.

It works well. I built a bracket to mount it into my truck. It would be nice if it had a rechargeable battery in it. It only works if it is plugged in to a usb charge.Also it is fairly accurate. It may read 3km h higher than you're actually going

I used this as my car doesn't have a digital speedometer and this is pretty accurate. So instead I just put this near my dash plugged in and used it and it helps out a lot knowing your speed quickly.
