Review on 🚗 VJOYCAR C90 Universal Digital Speedometer Car MPH GPS HUD Heads Up Display – Enhance Driving Safety with Odometer, Overspeed Alarm, Fatigue Alert, and Large 5.3-inch Screen for All Vehicles by David Forleo

I have to keep in mind it only cost me $29.00. So I might give it 1/2 star. I have a speedometer on my car. for now. I connected another to the vehicle's computer. and this third. I wanted a more accurate range. then it gets confusing. Speed up to 60 km/h, all three sensors are within a mile of each other. When it hits the freeway, it becomes a problem. Dashboard = 85 mph, computer reading = 72 mph and this unit = 76 mph. I still don't know how fast I'm going. PRO: 1: It seems to work. see the rest of the review. 2: Plug and play. 3: large display. 4: Easy to install on dashboard. CONS: 1: The screen is big but blurry. I always think I forgot my glasses. 2: There is a lag in the up and down speeds. 3: It is difficult to set up. Despite the instructions, the button sometimes does not work or randomly performs a different setting. 4: THIS DOES NOT COME WITH A CIGARETTE USB ADAPTER. Yes, it is a USB plug, so need to pay extra. 5: The power stays on even after the key is removed from the vehicle. So if you have an adapter that stays on it, it will continue to work. 6: At night, the approaching lights will confuse the sensors so they become bright, then fade and repeat. CONCLUSION: I have buyer regrets. I want to save my money and invest in a GPS navigation system. at least then i will be able to view and accelerate.
