I've had my Omnitech GPS receiver for close to two years. In that time, it's helped me find my way to a lot of places that I never could have found on my own. BUT--at least half the time, I have to reinitialize the unit because it has so much trouble finding a satellite fix. And then, although it always gets me to my destination, I find that it doesn't necessarily get me there the fastest and most efficient way. I would look for a different brand if I were replacing this unit.
