When I first got this, I was skeptical because I've tried similar gadgets that didn't live up to the hype, but this one has been a pleasant surprise. The projection is crystal clear, even in bright Arizona sun, and it's made driving safer since I don't have to look down at my dashboard. As someone who travels a lot for work, the direction feature has come in handy more than once when I've taken wrong turns. The speed warning is firm but fair—it's saved me from a ticket or two already. Overall, it does exactly what it promises without any fuss, and I'd recommend it to anyone tired of squinting at their speedometer.
- Pros: The display is incredibly bright and easy to read, making it simple to check my speed without straining my eyes. It accurately tracks my speed using satellite signals, so there's no guessing involved. I also appreciate the built-in direction finder that helps keep me on course, and the alert that warns me if I'm going too fast—it's like having a helpful reminder without being annoying. It works well in my car and seems versatile for different vehicles.
- Cons: It seems a bit pricey for what it does, and I had to spend some time figuring out the setup, which wasn't as straightforward as I hoped. The alert can be a bit loud at times, which might startle me if I'm not expecting it.
