Review on ACECAR Universal Dual System 3.5 Inches HUD - Head Up Display for Car with OBD2 GPS Interface, Speedometer, Engine RPM, OverSpeed Warning, Mileage Measurement, Water Temperature - Suitable for All Vehicles by Sheppard Priest

Changed from 4 stars to 1. Although it's a bright display, it's not visible in daylight unless you bring one adhesive reflector on . After a while I had a few days when my car battery died not knowing what the problem was, it started to appear more frequently. I took it to the store and the battery was dead. So I bought a new one. The same slows down a week later. Luckily the battery was still under warranty so I was able to replace the one I bought. My mechanic eventually got to the bottom of the situation and noticed that the speedometer/OB on the reader stays on when my car slowly shuts down. finally killed my battery. I spent about $400 to pay my mechanic and buy a new battery. I definitely want to return this item, but I can't. Please take my loss as a lesson and don't buy this item! Thank you, dear car friends!
