I don't understand what vertically stick means.... anyways when I stick it as shown in the pictures the reflected dashboard on windshield get more clear, please advise if this is what meant by vertically stick..The user manual instructions is not clear and may be its a good idea to include some illustration graphics for the steps and have more clear instructions.The small warning ⚠️ on poly bag is hard to notice I suggest increasing the font and add the warning ⚠️ sign or eliminate the other port or have some sort of protection built in the system.The product quality looks good 👍 OBD display are accurate, brightness is good and auto adjust to light. Its easy to use.I will give it 5 star for the nice colors and display design, I love 💘 it ...The reflective screen sticker to be sticked to front shield.

Idk what these garbage reviews are from. Does exactly what it says does. Projects a working speedometer on your windshield. It has never been "slow" for me once. Has a sensor on it for daytime or nighttime brightness. Beautiful picture, easy to use interface and bright projection in sunlight. I recommend. Has a clock In the corner and you can even watch the rpm Guage fill up its pretty nice!I use it in a 2014 Chevrolet cruze.

Lights up nicely but it does not stay on all the time shuts off. So it bought a different one. Qiilu Car Head Up Display, A8 5.5''OBD II Car HUD Head Up Display Auto Windshied Reflective Screen

This product does not work wellIt hard to useDoes not give correct detailsAnd does display wellI don’t use it is udeless

This is a tiny display. It shows you cardinal direction, tach, speedo, and clock. All useful information.There the positives end.- The speedo and tach poll the ECU once per second... might even be every 1.5s. It is so badly delayed that it really isn't useful for around-town driving speeds; at most, you'd be able to use it for highway cruising, where your road speed and engine RPMs aren't changing much or quickly. But, everybody has cruise control (although many folks choose not to use it...), which means, if you need steady road speed, you already have something that does that. Bringing it a little closer to your field of vision isn't really a benefit.- The cardinal directions are so tiny they're unreadable. The letters are half the size of the bottom row on an eye chart. For a device that's supposed to improve safety by putting critical information closer to the center of your field of view, it just doesn't make sense to include any instruments that are unreadable because they're so tiny.- It shows the car's DC voltage for the first 20 seconds after startup. It's not a problem; it just useless. Unless you're trying to diagnose your car's charging system. But there are other tools that do that for you. I don't need or want to see the car's voltage in real time every time every time I turn it on. I can't imagine who would.- The tach only shows denominations of 500RPMs. That, together with the unacceptable delay in data refresh from the ECU, means that by the time it shows one bar, your engine could realistically already be turning 2k RPM faster or slower before the next reading shows.Despite the relatively very few options for this kind of device, and this one DOES function (at least, mine does) - I have to give this an extremely poor rating simply on the basis of the very slow refresh rate. The delay is so significant that the tach and speedo are just useless while you're accelerating / decelerating, i.e., around town driving; and in highway driving, the overall concept is pretty well useless anyway. There are far, far better options available for roughly the same price.
