for the price its a very good product, i delivery pizza and use the gps to get me to the houses quicker then the other drivers. This has increase my tips and driveing times so that i can now make more money then i did before. One critic i do have is that occassionally it will start to freak out and say im going on a completely different other road, but it only last about 2 seconds and im right on path again so its no big deal. anyway good job i guess.
