I am frustrated by this system. I suppose when compared to one of those other systems (like Wii or DS) it is a bargain but I resent the fact that if you want to upgrade, the cartridges for older kids are not compatible with this system.First, for those of us who didn't want our children to watch TV until they were 2, it's pointless. We received this as a gift for our son's first b-day and before I could stop my husband from tearing into it, he had opened it up and made it impossible to return.Now that we are comfortable with our two-year-old using it, I am not impressed with the graphics OR the audio.All the cartridges compatible with the system are labeled for 18-36 months so now, my son would only get a years worth of usefulness out of it IF we chose to keep it and use it.Don't waste your money.
