My cars speedometer is dark, and following the needle is distracting. I was hoping for a digital speedo but it was not included. I looked at several GPS devices and chose this one. The price was right for a test. Amazing how low the prices got.I got a cigarette lighter to USB converter to power this unit. My other ports were being used. The speedometer picked up the signal right out of my garage, I was surprised how quickly it connected. I live in a flat area without any mountains, tall trees, or tall buildings to block the signal. The unit is all preset for MPH and does not have any switches. Truly plug and play.The readout was stable and easy to read. These devices are more accurate than cars speedometers, so unless you have a calibrated speedometer comparisons are iffy. Recommended!

Its easy to read as in plug and play. Only gave 4 stars because it took about 15 mins the first plug in for it to actually tell the speed. After a few uses it takes less than 3 minutes.

Too expensive, on Ali express 55 ryals only

UPDATE 8-13-2024: I still have this and it still works great. Accuracy is excellent. I don't have any issues with brightness at night. Strongly recommended if you need one of these. (EOU) I absolutely love this HUD! It is easy to see. Bold bright green digits. Nothing else. No clutter. Set up is as easy as plugging the USB cord into a type A port in your vehicle and plugging the other end into the HUD. The cord is very long. The adhesive pad is very sticky but it's the type of adhesive that you can remove an object from and still use both. As for accuracy, I noticed at higher speeds (about 55 mph) the HUD displayed maybe 1 mph faster than my vehicles speedometer but I am not sure which is correct, my vehicle or the GPS. A 1 or 2 mph reading is not enough to cause me to return this product. It is keeping me at the speed limits and moving in traffic safely so that's what's important to me. My vehicle speedometer is very difficult to read in the daylight. I found it necessary to modify the HUD a little by adding a "base" to it. When I first tried it out it would fall forward as I left a stopped position. I wasn't using the sticky pad then because I hadn't determined where I wanted to place the device yet. But I liked the location of the little tray on my dash and so I began testing it there. The base that I found was an approximately 2" plastic lid, black in color, from one of my wifes makeup jars she had saved and let me have. I put the sticky pad in the center of the lid and then centered and attached the HUD to it. Tipping over problem solved! I have to route the cord still. I have adhesive clips to do that with. Be sure to follow the initial setup instructions carefully. When you first plug the device in, let it communicate with the satellite for initial GPS coordinates (I didn't drive until the device was completely booted up). That data is "saved", the manufacturer has told me. If you unplug it on another day for some reason, your initial coordinates are there when you power it up again and use it. I unplug mine and hide it so as not to tempt a thief into breaking into my vehicle and ransacking it. I don't keep anything of value it my vehicle but I don't want my window busted in either. A word about the temperature range. The manufacturer has told me that the range printed is celsius. So, that 70 degree high end range is about 160 degrees fahrenheit, which is about as hot as a closed up car will get normally. Vent the window. I have not noticed a "brightness" issue at night when using it but that may be because of my placement on the dash. But that would be an easy modification. A piece of film hanging in front of it. I like this unit because it just displays speed. There is no other car data to clutter it up, like my instrument cluster. It is portable. I saw what seemed to be identical HUD's but I chose this Seller's product because it was a "2023" model. Seemed current to me and some comments I had read about other similar products with faults from those users indicated an item needing better internal components. So, I paid $3 more for what I believe is an up-to-date product that suits my use. A word about product customer service. I have been in touch with the company (and seller, VJOYCAR) and their service is A+ rated in my opinion. They are prompt to reply and answer any questions. They are very polite. The product is made in China (as are most US goods). I am completely satisfied with this product. It is simple, it is easy AND it does the job. Highly recommended. K & D UPDATE: I am still using this product and it is working absolutely great. I am totally happy with it.
