This is a cool little gadget, but there's a few things you should know. First, you're not buying this for its practicality, this isn't going to replace your speedo. Secondly, I've read a lot of reviews of other devices and found a lot of complaints about the accuracy and response time of the speed from the device. Let me clear that up by saying, there's no speed measuring sensor in the device whatsoever. You're simply buying a project that takes zero measurements itself. All the measurement is done by your car, which is transmitted to the projector through the OBD II port and it simply projects what it's told to project. Therefore, it's unfair to give these things a bad review because the speed is wrong or it has a small latency since your car does all the measuring. As far as visuals, this thing is plenty bright especially at night, and I only ever had trouble reading it in super direct sunlight, but it's really in its full glory at night.The reason I didn't give them 5 stars: the speed offset. Like I said, the car's computer is responsible for the speed measurement, not this device, but they could give you a better way to change the speed display if it's incorrect. Right now, they let you scale your speed by some percentage factor (so if your speed says 10, but your real speed is 11, you could set the percent offset to 110%). While this is a step in the right direction, a proper offset would include an actual offset, not just a scaling offset. To get a bit mathy with you, they've set a y=m*x offset whereas they need a y=m*x + b offset. This would mean that if your speed was only off by 2mph for all speeds, you could simply adjust all readings by 2mph. Small issue but it could really make the speed reading more accurate. The accuracy of mine is centered around 40, but it will be as much as 5mph high around 85 or so, and slightly off around 10-20.Overall, I'd get it again but only for cool factor; know you're not buying a precision measuring device or a speedo replacement. ### ⭐⭐⭐⭐ Nice adds on for your car. *by J***A on Reviewed in the United States on February 17, 2019* My brother has a lexus and it is already comes with something like this. It is very nice that when youre driving and the speed is there within your sight that you dont even have to roll your eye down to look. This thing is a similar thing to adds on for your car. The installation only took me about less than 10minutes to complete. It is very straight forward install, just hook up your obdii and run the cable to your gear. ### ⭐⭐⭐⭐ Works well, except disappears when wearing sun glasses *by M***L on Reviewed in the United States on March 11, 2019* Works well. At night and cloudy day, nice bright display. Washes out a bit on sunny day, but still visible, disappears when wearing sun glasses (not so good). Got it for speed display and MPG. Speed display is great, MPG is displayed as liters/100km. OK, had to make conversion chart, but over time I can convert in my head. Does what I purchased it for. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/41444799-trainshow-a8-head-up-display-5-5-obd-ii-car](https://www.desertcart.gr/products/41444799-trainshow-a8-head-up-display-5-5-obd-ii-car) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-31*
