I purchased two of these sound puzzles and neither has worked well since after the first few days. The sounds come on intermittently and often it isn't the correct sound for the animal. If your child is into the sound with the animal it will be very disappointing.
Unfortunately, after the first two days of use, the sounds work intermittently. And when they do work, it's not always the right sound for the animal. My granddaugther loves hearing the sounds when they come on but it's very unpredictable.
