My two year old son was very excited when I bought him the desk, but he quickly lost interest. He had to use the awkward pen to touch the green go circle on each page and sometimes the pen didn't work correctly. We tried replacing the batteries, but to no avail.We bought the Fisher-Price PowerTouch. It is much better. Not only will it last longer because of the expanded age range, but it came with 2 books, instead of 1. It is much easier to hold and operate. I highly recommend you spring for the PowerTouch. The extra $10 more than pays for the 2nd book alone.
