I have had it for about a month and a half now. In summary, I will say that it does the job, but:
1. It does not comfortably hold weight. The fact that the packaging photo states that it can hold 40 spice bottles is completely "fake" in my personal opinion, as I have 10 (4 of which are larger) and it rotates with difficulty.
2. The assembly does not come with instructions, you have to guess how the pieces fit and connect. After trying different things, at some point you start to suspect which pieces connect with which and where they should be placed. On the other hand, if it doesn't cut a little from them, you might be looking at it without being able to figure it out. A simple page with photographic representation of the assembly would save time for everyone.
3. Extremely fragile pieces in the assembly - in fact, probably for this reason, it had two extra vertical arms. Especially if someone doesn't understand from the beginning how one piece fits, it is certain that they will end up with a piece in their hand in their attempt to connect/disconnect it with another.
In its pros, the clever design allows for spice jars of different sizes.

It is exactly what it shows, I have been using it for months now, having organized ALL my spices. It has adjustable height. Very good.
