## Customer Reviews

### ⭐⭐⭐⭐⭐ Smartmax Building
*by S***W on January 9, 2026*

My grandson loves this item

### ⭐⭐⭐⭐⭐ Great toy
*by S***R on February 13, 2023*

My grandson picked this out because he’s had other toys from this brand. He just loves it.

### ⭐⭐⭐⭐ Not easy to play with
*by K***5 on January 8, 2024*

These looked super fun, and my four-year-old thought they were great. Then, after about 10 minutes he was so frustrated because they kept falling apart. He couldn’t build anything and keep it together long enough to play with it. The magnets are decent, but I would say these are more for age 8+. Small hands just can’t hold it together well enough with the strength of these magnets.
