It is very easy to assemble, no screws needed, and each shelf can hold 5-6 shower gels or even more shampoos. The package includes 4 hooks to place them wherever needed on the shelf or side. I don't have an opinion on durability over time, but for the price of €13, it is very good and convenient for a bathroom with limited space. I bought 2 more to place them in the cabinet under the kitchen sink to gather all the small cleaning items such as sponges, wire brushes, cloths, etc. The wheels are very useful, just make sure to place the heavier items at the bottom.
