I purchased this radar detector a while back (months and months ago) and its worked flawlessly. It has indeed prevented many a speeding ticket, and its always fun to find out where the police are hiding. This model has a lot going for it; the text display is wonderful, it has three settings (bright, dim and dark...dim is best for night) and a battery saver! Here's what I don't like about it...it doesn't remember your last settings when you turn it on and if you mute it, it stays muted from then on...and will not make a sound again unless you unmute or turn it off/on. I would prefer it if it muted for just that one band and automatically started beeping at the next band it picks up. But no one is perfect, I'm happy with the product...pick one up! Helpful tip: make sure you don't put it behind your windshield wiper -- it obviously won't be able to see anything. Enjoy!
