Review on 🚘 Enhanced Arestech 5.5" A8 OBD2 Windshield HUD: Display RPM, MPH, Fuel Consumption, Temperature & Speeding Warning by Scott Gendron

Very unfair reviews here, be the first/last review you read on this product. I read all the reviews and here is my answer: 1. This is not an app, it doesn't work with your phone. It simply reads information from your car's computer and translates it into graphics.2. The speed is sometimes inaccurate because it takes some time (1-2 seconds) to transfer information from the computer to the device. Also, the manual says you have to adjust the errors through the menu. So if the device reads +3 miles per hour, you need -3 for it to read the exact number.3. For people who buy this and it doesn't work, open the hood before buying and if you don't see anything that says obdII it WILL NOT work. Do not rely on the vehicle list provided by the seller, it is incorrect.4. In direct sunlight, there is NO reflection, it is invisible, direct sunlight means the sun is shining on the device, otherwise it looks good in the daytime.5. If you see double it means your glass has been factory tinted, you will need the plastic reflector provided, use a scraper and water, it looks fine.6. The unit itself is flimsy and poorly made, what a shame, I see when people say it stops working after a while, mine stopped working the first day and is now not working. I'm going back to Amazon to get a new one. I really hope the new one works well. The device looks great when it works and when you point it straight at the reflector it's a great concept and the numbers are pretty accurate. The thing is a bulk product from China, the quality is not very good, but use it for a few months and be ready to buy a new one, anyway the price is not bad.
