Review on 🎢 ROKR Marble Run Wooden Puzzles: Engaging Hands-On Fun! by Alexander Chavis

I have collected almost all of ROKR's mechanical puzzles and found them to be all of excellent quality and with good instructions. This marble puzzle stinks of haste and lacks quality, matching pieces and clear instructions. I suspect that putting some of the components together correctly would be a real, if not impossible, challenge for anyone not very familiar with this type of puzzle. While I've really enjoyed collecting other ROKR puzzles, I have to say this one was disappointing!
