I bought this stand a good while ago. I used it and then sold it on. There were a few things that were not great. The feet were not foldable, so this stand was not great to bring along. `the lowest setting was too high for sitting. I need to look down on a stand due to varifocal lenses. So for standing up it was ok but not for sitting down.
I ended up buying a stand which can go very high to very low.
