Level setting, nothing very complicated, there has youtube videos that explains very well. I started completely, and it took me say 3 or 4 hours accumulated. No microphone possible settings but almost (not need all down to adjust so it goes fast).
Turning to the subject itself.
On manufacturing, no worries, it's solid, it weighs (really) its weight and frankly you have to go hard to break the (failed yet;)). The levels on the fixing screws on the head frankly useless, but even they live in are metal, and inspire confidence level fixing precisely.
Besides, I invite you to prefer this round screw system rather than flat steadicam other stuff cheap. Indeed, it still has a in the central tube and that seems to be the weak point of the object, even if with some precautions to have no worries.
At the (small) negatives now, first we must tinker around. Upon opening the package, the counterweight (bottom of the tube) was not in the axis of the head, and Guimbal (the handle which rotates in all directions) had 1mm of play. Setting can result. But it makes up no worries. The base unscrews therefore can re-focus. The Guimbal also disassembles and just thicken slightly around the bearings to fix the problem without altering the fluidity.
Once done more worries, you can really have fun and quality plans. Sure there will not be the level of a pro stuff, but frankly that's enough if you do not plan to run a super-production
HOWEVER ATTENTION: with this steadicam, you must ABSOLUTELY invest in a quick coupler plate (Manfrotto 323 style is the one that I took and it's perfect) otherwise you will never use you because you will need adjust each time. With a quick release plate is one rule once and that's it.
This is the first purchase of the sort, and I do it again without hesitation because after about 1 month of use, I'm still really pleased.
Finally steadi very good at this price, the Search result is bluffing but only if:
* To buy a quick release plate
* Tinker a bit if yours present the same kind of (small) fault than mine.
