Adds a huge benefit of being able to preview and control your Hero2 from a wifi enabled device, range is about 25-50 feet maximum which allows you to control cameras that are in another car, or on a tripod quite a ways away. Wish it would have worked the same way on a Hero1, but oh well, still works with a remote.
When I purchased these they were about $40 shipped, making them a great deal, currently they seem priced a bit too high considering what hero2s sell for these days ($125-150). No one is going to buy a used $150 hero2 and a $100 wifi bacpac.... they're just going to buy a white or silver edition with wifi built in for $250.
