I bought for my almost 3yr old boy who has SPD(sensory processing disorder) and he loves them, as does my 6 yr old son and myself. They are perfect for gripping, rolling, throwing, massaging and they are not sharp or harmful. I only gave 4 stars because it would have been better if they were all different sizes. 4 stars

These are really great. They are about the same size or a tad larger then as a softball with the prickly points added on. As a previous reviewer stated I bought these for a child with a sensory issue as well. He has fun rolling them between his hands and against his face. There are hard but not hard enough to harm or cause discomfort. They are bright and colorful. These balls also seem very durable. I am not concerned about them falling apart. My younger two children (ages 2 and 4) love them as much as big brother.

The only reason I am rating them 4 starts versus 5 is I would have made them just a hair softer and they seem a tad on the pricey side. Minor quibbles and overall very good toys. 4 stars

This product was a win for my infant. It was a gift for his first birthday. The nubbies or spikes on the side are stimulating and he enjoys rolling these lightweight balls on the floor or playing catch. The balls are light enough to avoid damage if they're misthrown in the house. Perfect, right? I think they'll hold up well. They've be chewed on (by the baby), thrown by the older brother and stepped on by Dad. Survived all. 4 stars
