Picked up The Tike as a desk piece and I still can't get over how heavy it feels for its size. Machining quality is excellent too.

★★★★☆
Great little conversation starter for the office. Shipping was fast and free, I just wish there was some flexibility on returns since it's a bit pricier than I expected.

The cube itself is solid and well made, but the all-sales-final policy made me nervous ordering a size sight unseen.
