In my case, it was exactly what I was looking for.
I wanted three elegant shelves to mount on the wall for supporting some Mercusys Halos and distributing wireless internet throughout the building.
Well, the size according to the specifications, the build quality is good (although Chinese), easy assembly, the accessories in the package were more than enough, and the price is good.
Final conclusion, what they advertise, they absolutely support.

Excellent. I would have liked them a little bigger, but they serve their purpose just fine! The tails are a bit "rotten" lol, maybe you need to get some new ones! But other than that, it's a very good purchase. I use them in the kitchen for coffee jars, etc.
