Two questions for those that have the Intensity:
1. Does it hold air tightly when inflated or does it slowly escape? I just got mine and it doesn't seem to hold air tightly. I'm assuming mine is defective but wanted to check first.
2. Does the connection between the shaft and handle seem unstable, but only when inflated? It may be intentional because it almost feels like there is a rotating joint inside, but I wanted to check with everyone else. When not inflated, you can't detect it at all. But when it is inflated, I can feel little clicks as I bend it a little in each direction, almost like a ball and socket joint.
