Q:Does the overhead cable tend to get in the way of moving around or storing the headset?

A:It depends on how much you are reeling back in when your HMD is not on. You get enough mounting hardware to make an endpoint triangular tension on three reels which makes for extremely easy use when you are in VR. If you set it up properly you shouldn't have much cabling in the way. If you are only connecting one reel at the end you might get a little more interaction with the HMD cabling.
Storage is trickier. If you are storing your HMD near the last connection point(s) of the reels then you shouldn't have much trouble with any cables being unmanageable. If not you can either disconnect the loops around the cables for your HMD or just remove the reels from their mounting hooks. Personally I just take the reels off the hooks so they stay connected to the same points along the cables to my HMD. When I am ready to use it I just put them back on the hooks and I can hop in without tweaking the setup.

Q:Does anyone have a reccomendation for an adhesive (like 3m Command Strips) that can be used for the ceiling that won't ruin the paint on the ceiling?

A:I used the .5 lbs command strip hooks (the base is plastic and the hook is a separate metal piece). I wasn’t sure if they would hold up to being tugged on but they have been up for over a month of almost daily play and are working perfectly! I didn’t use the supplied adhesive hooks out of fear of ceiling damage.

Q:Have you used the adhesion hook? How does it work? Is it a suction cup or sticky tab?

A:Sticky tabs. Very strong, as long as your ceiling isn't especially textured.

Q:What size is the Allen wrench?

A:No need for an allen wrench.

Q:How well does this stick to bubble ceilings?

A:You need to anchor them in. Don’t Try to use adhesive on that. My ceiling is textured and they are anchored in very well.
