It's not for much, the assembly is easy in terms of logic but time-consuming due to the countless screws that need to be separated from the parts. The quality is mediocre, it easily bends if you apply pressure. It definitely needs screwing. I believe that it's better to spend an extra 5 €, maybe even less, for something with solid columns and more durable

3/5 The instructions were wrong, but I managed to fix it because I have assembled many similar ones. The construction is average, proportional to its price. It has screws. Many of them. Other products in the same category are screwless and can be assembled in 5 minutes. This one (I bought 4) took me 20 minutes per shelf, due to the screws that need to be unscrewed first...

I assembled 8 bookcases, but I couldn't finish any of them in under 1 hour (about 60 screws each). They require screwing into the wall. Based on their price, they are worth it if you have patience and they are intended for placement next to the wall.

Excellent purchase for its cost. It can withstand the weight mentioned as long as you distribute it to the edges of the shelf and not in the center. For maximum results, it needs support on the wall either with screws or in some other way. Overall, a very commendable product. It was used in courier company offices with excellent results.

Needs help.
It's not for a lot of money.
It plays a lot when assembled. It needs support at an angle on a wall, I don't know anything though.
For simple things it does, I don't know if it will need painting with varnish or something to prevent rust, etc. from humidity. I put wood on the shelves and it helped a lot. It stands better now and lifts the weight correctly.

Very good for its price. Although it doesn't convince during assembly, it looks fake, when it is set up it is quite sturdy. To be well stabilized, it needs to be screwed to the wall.

During assembly (which is not difficult or confusing, but time-consuming with ~45' required time) I thought I was screwing aluminum foil. As a construction, it doesn't impress you. Be careful with the sharp edges, they easily cut your fingers. The most significant drawback is that the side supports are not one-piece 1.5m but you connect 2 sections. This way you can play with the overall height, but I think you lose stability. To have peace of mind, I screwed 2 shelves side by side and secured them to the wall. Time will tell if they will hold up. One thing is for sure, with a small budget, I organized my things. I hope they stay organized.

Update 04.10.22
Time has shown that it holds up just fine. I bought two more to organize a storage room. Connected to each other and secured to the wall

For the money, it is excellent. It looks a bit fake and like it will break, but it withstands quite well and within the limits stated by the manufacturer. The assembly is quite easy and I highly recommend it.

For the money, it is excellent. Compared to another one I had bought, this one seems quite fake and not as stable. Personally, I got it to have 15-20 kilograms on each shelf and I don't need something stronger. The instructions are incomprehensible and I threw them in the trash from the first minute. Nevertheless, I assembled it within 40 minutes.

Well, it's worth its money but it doesn't assemble easily at all, we've been here for 2 hours and we've only put up one shelf, the design is confusing and the assembly gets a 6/10 only because it's very difficult to put together but it's great value for money

Just assembled two ....I can't wait to tidy up my storage.....
Great value for money and more than that....
