The sticks in the video are with the Gen 2 thicker steps which are machined with tighter tolerances. The thinner Gen 1 steps moved ALOT and squeaked/popped loudly and I was ready sell or violently wrap these sticks around a solid immovable object. After talking to the owner of TN, he sent me the Gen 2 steps free of charge. All around a great set of sticks, great guys and very responsive with questions or concerns. I highly recommend!
