Query: worth every penny, great learning tool

I bought this for my daughter 2 months ago, when she was 20 months old. It was love at first sight. At first, she just enjoyed putting the letters in and taking the letters out. Then she became interested in pushing the letters to see what sounds they made. A month ago (one month after receiving this), she started pointing out letters on signs and in books and telling me what they were!! She continues to play with this every single day, and she is now trying to sound out letters wherever she sees them. This is, by far, the best "toy" we have ever given her.
