I have a Titanmen Crankshaft (great toy) and have no problem getting that the whole way in if I take my time. It's a long toy but tapered so I figured I'd try something more challenging.
Bought a Cisco and tried it out today after warming up with the Crankshaft. I could get it maybe 2/3 of the way in but that's it. And that was after playing with it for maybe a 1/2 hour.
Any tips on how to get this thing the entire way in? I don't want to end up in the ER, LOL.
