We have the V tech V Smile system for our 4 year old and it is the best thing!! He has learned so much from those games, he is now cognitively far advanced for his age. His 3 and 4 year old teachers have both asked me how he has learned so many skills, for example sorting, math, counting, all his letters, opposites, sames, etc. And, while I take some credit, I always point out the V tech V smile system. It really makes learning fun to him, and he wants to play it a lot. We actually limit the use now to 1 hour per day. I think it is a wonderful thing. We have the Jammin Gym class mat, and he loves it, but it has already broken twice. So, I wouldn't get that part of the system.
