Chimpsy Camera Classes

There is a groupon for Chimpsy classes here and I was thinking of getting one for my wife. Anyone used their service before that can comment on it and how good it is? I would be looking to get the beginner DSLR and intermediate DSLR classes for her as she has been wanting to take some classes for it but we couldnt really afford the more expensive ones. If the service is reputable then this would make a great Christmas gift for her. Thanks!
