Are ROKR wooden mechanical puzzles worth it?

Mainstream verified-purchase reviewers rate ROKR kits highly (typically 4.4–4.7 stars), and r/Hobbies threads call out ROKR, Rolife and Robotime as the best-designed brands in the category. However, r/ugears and other specialist threads flag quality-control concerns: thin laser-cut plywood pieces can snap under pressure, and motorized features sometimes fail. Treat them as a craft-build experience first and a working mechanism second.
