Review on Color Tree Universal Speedometer Windshield by Jeff Langford

Easy to use. The device worked the first time. The HUD is pretty nice. Only sunlight coming from the front makes it difficult to read. However, the control switch is difficult to operate. 16 parameters can be set. You have to scroll through them one by one by clicking the control, but they're not in the right order. Turn the knob to change the setting. But the controls may get stuck and you may miss. Much time. The speed display is inaccurate and you need to go into setup mode to adjust this. The manual is almost illegible, which takes time and requires guesswork. All this makes recommendations difficult.
