Pros: Works without a problem. Finds the satellites quickly when you are in the same area, if you fly around the country it takes a little bit to get situated but hasn't been more than a minute or two for me. I fly a lot and it is usually ready to go before I'm ready to pull out of the rental car lot.

Cons: Could do a better job rerouting when you miss a turn or if there is a construction detour - it keeps wanting to have you make a u turn for quite a while before it figures out who's the boss.

Overall Review: I haven't had any problem with mine and I use it extensively for business travel. I'm in multiple cities per week and I use it religiously. I can only imagine how much easier the beginning of my career would have been with one of these things.

Pros: nice price

Cons: wireless not working. Christmas gift that doesnt work - not ideal. Hopefully Newegg or Lenovo makes it right.
