Andrew K. ★★★★★

These have become the most-used toy in our playroom — my four-year-old builds towers just to watch the colored light bounce through the faceted gems inside each block. The acrylic holds up well after a few tumbles off the table, too.

Leo ★★★★★

My kids hold these up to the window just to watch the light come through the faceted gems, and then they actually build with them for an hour. The acrylic insets are set deep enough that they've survived plenty of drops already.

Timothy ★★★★☆

The faceted acrylic gems really do throw little rainbows across the floor when the afternoon sun hits them, which my kids find endlessly fascinating. My only gripe is that the corners are sharp enough that I wince a bit when the toddler stacks them too fast. Still, they've held up well through weeks
