My 22 month old twins LOVE this puzzle! They鈥檙e especially obsessed with the rooster sound lol! I鈥檓 amazed at how quickly they caught on and were able to play with this. It鈥檚 a great educational toy and I highly recommend it. I understand the other reviews that say that it doesn鈥檛 always work, and I thought the same, until I read the description again and realized that it鈥檚 light activated! If the room is a bit dark, the sounds don鈥檛 work but if you play near light, it works perfectly! Hope this helps :)
