"Very nice, make sure your phone is compatible."4.5 starson by mlissne
Pros: Small, Good Battery Life
Cons: Occassionally slightly off course
Summary: I really like this thing. I took it to Ireland and used it with google maps to navigate around. You don't need AT&T's GPS system to use it. On rare occasions it will tell you you're about 40 feet away from where you are on the map, but this is rare and not a big deal. My biggest pet peeve was that I had to hack my T-Mobile Dash to get it to work even though Globalsat says it's compatible. Now that it works though, I'm very happy with it.
