3.5" Car HUD Head Up Display with OBD2/EUOBD Interface Plug & Play Vehicle Speed KM/h MPH, OverSpeed Warning, Water Temperature, Battery Voltage, Mileage Measurement

Installed in a 2015 Traverse in 2 minutes. Fooled around with placing it, getting to know it and adjusting it for maybe a half hour. First, short answer, -yes it works great. More on that later. Also, mine arrived already set to MPH instead of KPH, so apparently they've figured out to do that for units being sent to America so you don't have to bother doing it. Also, I am one of those people who just wanted my speed up on my windshield. I don't give a dipsy-doodle about anything else it can do and actually turned off everything else it can do. So this review is for it for use as a speedometer, which it does superbly. Before the glowing review part though, let's address a few things I read about in other reviews that had me wondering:1. Brightness/visibility: Consider first that every windshield is a little different, meaning how tall it is, what angle it's at, etc, -and that all contributes to how things (including the dash itself) reflect up at YOUR particular windshield. So anyone saying it isn't bright enough or can't be seen, -not true unless you either got a defective unit or happen to have an impossible vehicle to find a spot to place it. I left the cable loose and drove around for awhile trying out different places to put it and found what is ideal for me and my car. There were a couple places I tried that yielded "so-so" visibility, and I found several that were just fine, and one that's perfect for me. Driving directly into the mid-day sun I can still see it ok. Any other lighting conditions it's far beyond just ok. I happen to have crappy eyesight, so if I can see it at high noon, you should be able to as well! In fact, I would advise setting it up during mid-day sun, because once you find the right spot to see it then, you know you will be able to see it at any other time of day.2. "The sticky stuff doesn't hold it to the dash". Come on man! Maybe the sticky pads that come with it do or don't work, but I wasn't going to put ANY kind of adhesive on my dash that might leave future residue. Go to Wally world and spend 2 bucks on some command strips for gosh sake. Works great and will pull off cleanly some day if/when I want to remove it without leaving a trace! I still have some command strips left over for hanging pictures even. This stuff isn't rocket science!3. "It's impossible to learn to get around in the menu". Ok, first, it's not that terrible. Second, -how many things have you bought from China and have you EVER gotten a Chinese "manual" that anyone could clearly figure out without doing some liberal deciphering of what you think they mean? Push the button/"wheel" thingy in and hold it till the display goes to the number one. Now look at the little chart in the instructions which actually clearly tells you which number pertains to which function the unit does. move the button/"wheel" thingy up or down to get to the number that corresponds to what function you want to adjust. (Example: scroll to number 2 to adjust the calibration of the speedometer). Once at the function you want to adjust, press the button straight in. It beeps and the speed calibration pops up set to 108. After a little trial and error I set it down to 105 and it now matches my vehicles indicated speed on the dash exactly at 70 mph. Once you're done setting whatever it is you're adjusting, press the button straight in and hold it in till the display goes blank for a second. Let the button go and that's it. You adjusted whatever it is you were adjusting. Nothing scary or weird about it. Just typical Chinese instructions. And I would add that I doubt there's any better instructions with any other Chinese unit you're going to buy, so... - Like somebody else said, I won't be scared of the Chinese taking over the world until after they can make clear intelligible instruction manuals!4. "You can't turn off the overspeed alarm". That's true. UNLESS you scroll to number 8 on the menu and turn all the alarms off because #8 is for all alarms on or off... I mean... Not sure what the "problem" was supposed to be here ???5. I found absolutely no need for the reflective film. Whatever "ghost" image might be there is insignificant.Let's see, what else? I actually compared the readout from this, my dash, and one of those radar speed sign things by the side of the road. Result? You can match your speedometer exactly at say 70 mph, or at 30 mph, but probably not both, because that's just how speedometers work. It will probably be off slightly (1 to 2 mph) at either high or low speed so choose whether you want it right on at high speed or right on at lower speed. I chose to match my vehicle speedometer at 70mph, which puts my indicated 30 mph speed 1 to 2 miles per hour lower than the radar sign thing says I'm going. Close enough for the girls I go out with! AND, even the girls I go out with are smart enough to know that if this thing says 70 we're going 70 but when this thing says 30 we're actually going 28 or 29... Compared to some of the reviewers here, the girls I go out with apparently are rocket scientists!Conclusion/Glowing review: if you can live with a typical Chinese instruction sheet and it being right on at 70 and off by one mph at 30, I would have to say it works absolutely fabulous! It is SO nice to just keep eyes on the road while driving and adjust speed without looking away! -AND, the chicks will think you're a freekin rocket scientist for putting this sophisticated piece of technology in your car all by yourself! Win/Win/Win! 5 stars!

The media could not be loaded. For a better quality video, search SHEROX 3.5" Car HUD (A100) review on YouTube.I love this heads up display. I previously had the X5 HUD Arpenkin X5 HUD 3" which I also really liked, but it had too many things going on. For instance, the "red line" on the X5 is arbitrary and didn't match my car's and the RPM gauge would frequently flash when I was idle because it thought my RPMs were too low. All in all, it was a good product that I had for around a year and a half. The other HUDs on the market are even MORE cluttered and grotesque looking. Which is why you should buy this. Also, I am not being paid to write this review and I didn't get it for free. Just trying to help you make the right decision.So I had the other HUD for like a year and a half. Until I saw this guy. It doesn't say in the product title, but the model number is the A100. The only thing this displays is your speed, and it has a few alarms it can trigger. Watch my video for a more detailed review, but this thing is easy to install and setup and is very clean and elegant. It also came with 4 circular 3M double sided sticky tape that will hold it in place on your dashboard. The instructions are written in Chinese and then poorly translated into English but it's easy to understand what they're trying to tell you. You should buy this if you don't want to have to look down to see your speed constantly and you want something that is minimalistic.Also, I ordered this on a Tuesday and received it the next day (free shipping for prime members is great!). If you watch my video and you also have to remove your weather stripping it's as easy as giving it a firm tug away from the metal and then putting it back on is as simple as pushing it into place.

You know what? I actually like this thing. It doesn't have GPS, it won't alert you to traffic conditions and it won't give you turn by turn directions. Great! I don't need those things, as my phone does all of that. What I needed was a way to monitor my speed without taking my eyes off the road. This device does that job.Pros:-Visible day or night without reflective film-Cheap, but effectiveCons:-Annoying to program-Not easy to calibrate your speed to be accurate (But within 2 or 3 MPH at 70)If you're really pushing things and being 1 or two MPH over will get you a ticket, first, stop. Second, don't get this thing. Otherwise, it works just great.Also, they sent me two for some reason, but I'm not complaining.

This is installed on a 2022 Ford Explorer ST.What I like? Small, simple, stupid simple to install, bright. Really is just plug and play for the most part.What I don't like? 1) Double vision, even with the supplied reflective film. Though, I have to admit, the double vision is improved some with the reflective film. However, the reflective film is obnoxious. The video makes it look like that it's BARELY noticeable. But, it sticks out like a sore thumb. Wife hates it, she rather have the double vision and no film. So, we'll see how long this lasts... 2) The included instructions are an absolute joke. 3) Accuracy is a bit off... It's not so bad at lower byway speeds. But, once on the highway, it's 3 or 4 MPH off. Haven't had a chance to calibrate it due to the fact that the instructions are useless. But even still, what I've heard, even if I were to calibrate it to be more accurate on the highway, it SOUNDS like the lower speeds will then be off slightly.I don't know, there's a 50/50 chance of this thing staying in the car long term. This is my first aftermarket HUD. I knew $60 was going to be a gamble. Glad a tried it, gives me a good baseline. Might try it in my 2020 GMC 2500HD, see if I get any better results. But, I mostly got it for my wifes Explorer.
