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!

## Questions & Answers

**Q: what is the diameter of the magnetic balls?**
A: About 1.5 in, pretty much golf ball size

**Q: From the reviews, it looks like kids from 2 and up would enjoy these.  Any feedback on kids 5 to 7?**
A: Kids and adults enjoy these, in my experience.  (No, I do not work for the company that produces this, and I do not sell this or any other toy product.)

**Q: What size are the metal balls?**
A: I'm not sure of the exact size, but they do not pose a choking hazard for young children. I bought two sets for toddler classrooms. The children love them and they are safe to play with.

**Q: Does anyone know if these smart max pieces are compatible with the magformers version called “stick-o”s?**
A: The magnets should work together however the Smart Max are bigger and rounder.
