Review: Quality - Quality product, engaging and durable. Like the ability to put in dishwasher to clean.
Review: Great toy in and out of the bathtub - My grandchildren love Blockeroos. This is the 3rd or 4th set I have bought. They are expensive but they last and continue to be enjoyed in and out of the bathtub. Perfect for 2 yrs and beyond. If they want to bite them wait until that phase has passed since that can ruin them.

### ⭐⭐⭐⭐⭐ Fun and creative toy
*by A***R on June 19, 2025*

My 2 year old and 5 year old love this magnetic toy. The magnets are strong and work well unlike some other magnetic toys. While my 5 year old uses her imagination to create all sorts of cool things, my two year simple enjoys putting the magnets together and taking them apart. He also loves the ratcheting sound the magnets make when you spin them. Great buy for a variety of ages!!! Definitely plan on expanding our collection.
