I've had one since they first came out. Took it completely apart(recoil tube included) cleaned all the heavy grease off it, lightly lubed with a high quality oil, put it back together. Followed the instructions on "breaking it in" to a T, and have never had one issue with it. It'll cycle anything you drop in it. I'd bet a large portion of the ones that don't cycle just need a good disassembly and cleaning, and a light lube with a good oil before reassembly, and they would run just fine.
I think I'm an alright guy, I think I'm alright
