Lil Mynx Rotator Question-

Hey everyone. I inherited an older model Lil Mynx rotator. I have put it up and when we have it in spin mode, it is undoing itself so the tension is not there. When we put it up, I thought maybe we hadn't allowed enough extension to create the pressure needed. So, the next day when I put him up, I had him extended to the point where it took 2 of us to get him up and level over the slip pad. He was nice and tight at that point. However, he still loosened himself up to the point of "touch me and I fall over" I called Lil Mynx this morning, but they are closed until Monday. Has anyone had this happen? Or know what the possible cause is? He was purchased second hand by a friend and then given to me........So--Is it possible she bought a damaged pole? I won't put him back up as it is too much risk for safety....but figured I would ask you Veeners if you had ever heard/seen this.... The ceiling height we have mounted it too---is 10ft. When my friend purchased this pole, she was told it would safely go up to 10 feet. I am however thinking this pole is the standard lil mynx rotator that is meant to safely go to 9 foot ceilings. Is there any way to tell by measuring the extension piece? I have never used a lil mynx before, and I like the grip....but it is not worth the safety risk if he isn't meant for our ceiling height.  Thanks!!
