Bought for my daughter as a gift as she loves fidgets and Tetris. She loved it! It has been a year and she is having a hard time keeping pieces together. Absolutely buy again.Bought this to play with our 3.5 year old. We love to play it together and pop all the pop-its. Also entertaining for us parents.My 2 year old son loves this. Makes him have to sit there and think. He loves the challenge. It's fun to for all ages in my opinion.Older kids will like this because it can be challengingI bought this for my granddaughter who is very sensory driven. She loved it I actually took a picture of the assembled puzzle in case she couldn't get it back together but she didn't even care, she just liked popping them and trying to place them in the tray.This pop it pops so well! on both sides! Great for sensory!My kiddo's absolutely loved itLove it!
