Our 3 year old son loved the Word Whammer... except that it didn't recognize the letters properly, therefore encouraging him to spell words incorrectly, confusing him about letter identification and not complementing him on correctly spelled words. We returned the WW and got another one only to find it had the same problem. This was a huge disappointment as we loved fridge phonics. Do NOT buy the Word Whammer!
