You get what you pay for, but this particular product is not just cheap. It is shoddy, with many defects that are not related to cost reduction but rather to a poor manufacturing mentality.
First of all, the instructions... very small images and incomplete descriptions. I spent a whole day assembling it.
Some sealing rings were missing and I had to go buy my own.
Some screws simply would not screw in. I replaced those with my own as well.
There are some screws from the manufacturer at the bottom of the bin that stick out quite a bit (see photo), resulting in the sealing gasket not fitting properly and causing leakage at the joint between the top and bottom of the bin. I had to use a lot of silicone to limit the leaks.
Finally, there are shavings inside the frame's hollow sections. This doesn't really matter, but I mention it as yet another sign of sloppy and slapdash construction.
All the materials are the cheapest possible and overall it gives the impression that it could fall apart at any moment.
Do not buy it. Spend a little more and get something more decent or turn to another company.
