Pretty cool for the price but not perfect
Color: 5.5 HUD
I bought this for my RV before a cross country trip because my speedometer is hard to see with my sunglasses on and the tilt wheel down, which is what I prefer. Super easy, just plug into the OBD port under the dash. It comes with a small reflector screen like a screensaver for your phone that you affix to the inside of the windshield. It showed speed, RPM's, volts and water temp. It does read a little high....at 70 mph on the dash speedometer and with cruise set on 70, this devide read 75 mph. Error seems less (+2-3 mph) at lower speeds. Anyway I just mentally adjusted the math. It was a great help on the road, lessened the driver fatigue for sure. The instructions stated that it may read less than the dash gauges.....I don't know if it is because it is cheap, or if the data from the OBD port causes this. Either way it's a cool gadget. ... show more

This is simple to install and adjust to your preferences.
Color: 5.5 HUD
I found this as simple as plug in and go. It was already set to mph and calibrated accurately for my vehicle. The double image issue was so minimal, I considered not putting the reflective film on my windshield. Without the reflective film, it’s a bit dim, but not hard to see on a sunny day. With the reflective film, it is clear and in color on a sunny day. I am happy with it. I installed it as low on the windshield as possible and that works for me. I am not worried about the exterior mirror look, nor would I be concerned about explaining or demonstrating how it does not interfere with road vision to a traffick officer. You see right through it like sunglasses. ... show more

Easy to install, but it dies in the heat
Color: 5.5 HUD
Worked fine for about 2 weeks, then began to randomly change settings. Now it reads KPH instead of MPH, and when I'm on the freeway doing 55, it says I am travelling at 213 KPH. It randomly shuts off, restarts, or fails to turn on when I start my car. It is basically a POS that you should not waste your money on. ... show more

It's a useful basic device
Color: 5.5 HUD
I tried this alongside the ACECAR offering. This is the clear winner, for a couple of reasons. The speedo and tach are a little bigger, but are also quicker - it may poll the OBD-II data every 0.5s instead of 1.0s. There is a significant lag on the ACECAR offering that makes it largely useless for monitoring around-town road speeds. Also, the ACECAR unit only visualizes 500RPM increments, which, together with the delay, makes the tach altogether useless. By the time the ACECAR readout catches up your engine may have increased or decreased speed by 2k RPM. This unit reads out RPMs in 250RPM increments, and updates much faster, which, together, means it really is useful as a gauge at any road speed. It doesn't have cardinal directions as the ACECAR does; it shows fuel economy, but in terms of L/100km, which is not especially useful in the US. The only potentially useful aspect is that it shows you real-time economy, so you might get some sense of your general economy. It also has a trip computer, which is helpful, but again, in km only, so, it's not going to be useful with respect to your nav unit, maps on your phone, directions, etc. Engine temperature, in degrees Celsius, is also a useful reading, and may be consistent with your instrument cluster if you're in a European car. Given that it is bigger, easier to read, updates its readings more quickly, and that all of the data displayed is helpful (although the color scheme is a complete mess and it's only in metric / European units), the reasonable price, and ESPECIALLY given the lack of better competitive offerings, this is a solid 4-5 stars as of June 2020. I'm opting to add this to all of my cars that don't have a HUD. It's simple, easy and useful. ... show more

Read this first . Good/Bad
Color: 5.5 HUD
Very unfair reviews here, let this be the fist/last review you read about this product. I read all reviews and here is my response: 1. This thing is not an app, it does not work with your phone. It simply reads the info from your vehicle computer and translates it into graphics. 2. The speed sometimes is not accurate because it takes time (1-2 seconds) to transmit the info from the computer to the unit. Also, it says on the manual that you have to adjust the errors from the menu, so if it displays +3 mph on the unit, then you have to -3 so it displays the exact number. 3. For the people that buy this and doesnt work, before you buy, pop open your hood, and if you dont see something that says obdII, it will NOT work. Don't go by the vehicle list the seller provides it is inaccurate. 4. The reflexion SUCKS in direct sunlight, it is invisible, direct sunlight meaning the sun beaming on the unit, it looks good in the daytime otherwise. 5. If you are seeing double, that means your glass was tinted by the factory, you need the included reflector plastic, use a squeegy and water it looks great. 6. The unit itself is flimsy and made poorly, what a shame, i do see when people say it stops working after a while, mine stopped working within the first day, and is now malfunctioning, I am returning to amazon for a new one. I realy hope the new one works fine. The unit looks great when it works and if you aim it correctly to the reflector, it is a great concept, and the numbers are pretty accurate. This thing is mass produced from china, the quality isn't great but use it for a few months and just be ready to buy a new one, nevertheless the price isn't bad. ... show more

works good, but not good for Hyundai hybrid
Color: 5.5 HUD
I like that it delivered the info it said it would, but the manual and settings were a bit confusing. I had to return it cause I could not properly use it. I have a hybrid Hyunday and when the car shuts the engine off while still "on", the power is cut off to the HUD unit, and I would have to physically turn it back on when it came back. it is the fault of the unit, not turning on as soon as there is power and info. but not the fault of the unit when my car stops sending power and info while still in the "ON and driving mode" ... show more

It's a cool thing. but once you install it
Color: 5.5 HUD
It's a cool thing.but once you install it, it feels like your constantly looking at it than the street. Also you have to apply this reflective film which is a messy thing to do since it will have a lot of small bubbles, plus it looks awkward on the windshield to stick In a sheet of plastic. Also if you move your seat a bit differently then half Of the image is on the windshield than the film and then it projects everything double. Overall it's a real exciting thing to buy, but it's a turn down once you have it installed. ... show more

Worked exactly as expected
Color: 5.5 HUD
I found it slightly finicky to set up and get situated as I liked, as well as to secure in place. Once I had it set up as I wished it worked quite well.
