I have bought two stands at almost the same price to see the differences. This one is the larger one in the photo.
-- Assembly:
Very easy, this one does not have instructions inside (the other one does). You can place the shelves at any height that suits you. You can put two shelves on one side and leave one quarter empty to accommodate tall packages. You can do it as you like. This one does not have slots like the smaller one to hang chains or pendants. If you want to see what I mean, go to the link of the other stand that I have included below to see in its review what I mean. It is important if you want it for jewelry. Otherwise, we don't care that much.
Inside, it has rubber bands that you put on the joints of its parts to stabilize them. And in both stands, the rubber bands it came with were exactly what you need plus 2 extras for security. Look at the last picture to understand where the rubber bands go, without them, the stand won't stand because it is loose and the shelves can fall off.
-- Base Rotation:
This one is not that good, the base that it stands on is a small circle, the rest is in the air. Where I placed it, it won't cause any problem, I just mention it because the smaller stand is much more stable. The bearing it has is small balls on the base and this specific stand is not so well-made. The smaller stand, for example, slides and if you give it a little push, it spins on its own for a while like a top. This one doesn't do that and it also makes a little noise when you rotate it.
-- Size:
This one is slightly larger than the other one but I consider it equally functional and of course, it can hold more things, so if you have space, you can put it.
Obviously, you can use it for all your bottles or small packages. You can even use it in the kitchen for spices.

I give it 5 stars because it simply does its job, the smaller one is better constructed but it is also smaller at the same price as the larger one.
The other stand that I bought is this one and I also reviewed it there:
