Review on HUD Car Truck OBD II Head Up 🚗 Display – Color LED Projector for Speed Warning System by Alex Jones

I have replaced another device with this one. I am very happy. It will lag a bit on the RPM scale, but who buys a cheap HUD to get tach readings accurate to the minute. I want it to display speed and also use temperature and voltage display. The horn/alarm slows down a bit when I accelerate and rev up quickly. If I actually get a different directional guidance, I'll turn it off! It was accurate once the speed was calibrated to my car (I used the HUD app on my phone to confirm the speed, not the speedometer in the car, they are never accurate), it always worked as advertised. Nice little unit. It can be a bit difficult to see in bright sunlight, but it's not too bright at night to be difficult to see through. I've had the device for a while now, still like it, wish the display had a different brightness setting, at night I wish the display was dimmer. I live in the country and it's very dark at night. There are nights when I actually unplug my device to get a better view. This is not unique to this device! I had another brand of these that came out too early so I went with this one. However, the previous HUD I had was the same, it had a Hi/Low setting type that was sometimes too bright at night. ALSO don't lose your referral brochure. If you ever want to change a setting, you need it,
