Query: expensive

I ordered this toy, and couldn't tell that you needed to purchase an expensive piece of other equipment to use it, and i have purchased a LOT of leap frog items and it's always clear what equipment it works on. so now I have had to spend another $40.00 on a piece of equipment that doesn't have many games with it, and he will outgrow in one year. I would have been better off buying something else.
