I'm not convinced there's a "good" GPS on the market, but this one is as functional as any. It gets me to my destinations, but not always with the fastest or most direct route. It can't take into account the speed traffic is moving at, so the arrival time is often misleading (especially here in Washington DC). The mounting system for the GPS is weak, and if you don't have a perfectly flat surface, it will fall off. Basically, the only place you can stick it is on the windshield, which isn't a great option for everyone. My biggest complaint is definitely the route planning. We tested it side by side with my fiance's Garmin, and almost every time the Garmin picked a more direct or faster route. The Tomtom seems entranced with highways; even if taking backroads is faster, the Tomtom will direct you to the nearest interstate. On the plus side, it's not an expensive model, and if someone steals it out of my car I won't be out much money (nor will I be terribly upset).
