I'm so disappointed in this product. My great grandmother purchased this for my 2 year old and it's really a disgrace to the Melissa and Doug brand. The construction is fine but the sound doesn't function properly at all. You can just wave your hand over the puzzle and it'll shout a number. My daughter will go to put the number 12 on the board and as she's moving it over 16, it says "16" and she just looks at me like, "am I wrong, or is this thing broken?". We've since taken the batteries out so she doesn't wind up confused. She already knew 1-10 and about half of her teens and we don't need this thing screwing things up.
