Review: He loves it! - These are my son’s favorite toys. He takes the spider one everywhere. He’s 5yo and can easily transform it. The little arm comes off but it’s easy to reattach. The build quality could be better. My son has so much fun with it and I need to buy more. The size is a good size. Not too big and not too small.
Review: Good for price. - Wish they had these cool toys when I was younger for the price. It is a great toy quality seems pretty well, and for the age range. I’d say it’s about three and up. No small parts it’s pretty cute toy and the movement seems well transforms with ease.
