Great toy! Apparently for all ages. Lol
I bought this for my 4 month old for Christmas, just opened it up last week as he's developed more into playing with toys. Good news about the sounds, they're not too loud like most toys!! What's funny about this toy, while it is a babies toy, my 8 year old and my 13 year old regularly play with, too! They have both said to get them one so they're not taking the baby's away. I suppose they see it as a type of "fidget", my fiance has even spent time playing with it! Lol. All around great purchase!

Fun Toy
This is well built and safe round corners. I originally bought it for when our 2 older grandchildren visit they would have a toy to play ‘for’ their cousin. The 6 year old loves the challenge of getting colored balls into color matching tube. The 3 year old plays it as expected, laughing at silly (not too loud) sounds. Our 7 month old loves to play (while we keep toy steady). He gets very excited with sounds and colors. It’s a classic toy that will last a long time.

Great for 6-12 months, no setup required!
The RainbowKeys delights babies with colorful piano keys that play fun sounds and pop-up balls. It’s ready to use right out of the box with batteries included. Perfect for engaging little ones, it’s durable and great for sensory play.

Fun toy, great for sensory and motor skills development
Our baby loves this toy! She rolls to be closer to it. She has figured out hitting the buttons. She loves the movement of the toys inside.
