Review: Really cool toy! - This is a great set. It's very versatile and can be used with other sets from this brand. My one-year-old currently loves using the long magnets to pick up the balls. Maybe in the future he'll build with it! It seems like a toy that will stay a favorite for at least a few years, so it should be well worth the money! The magnets are just strong enough, and they're super safe -- they can't easily pinch those little fingers.
Review: Inspires creativity - Purchased for our 18 month old granddaughter. She loves them. She builds something new everyday! Highly recommend. Great quality!

A: The magnets should work together however the Smart Max are bigger and rounder.

### ⭐⭐⭐⭐⭐ Buy these!
*by V***A on September 5, 2022*

These are awesome - FAR SUPERIOR to the cheaper sets. These are sturdy, and the magnets are actually strong. This helps to reduce frustration in your kids while they play with them, because these actually stay together and can be effectively used by your toddlers, on up to bigger kiddos. Great investment - I’m planning to buy another set just to have more pieces!
