It has a slight transparency that lets light through, meaning it is not completely dark, but you cannot see inside at night when the light is on

The fabric roll wears out easily at the edge. When it folds, sometimes you need to align it. The plastic bases with the double-sided tape are not enough to keep it on the wall; after a few days, it falls. The solution is to nail it to the wall or alternatively screw it in with a screw.

The stickers that are supposed to hold the curtain cannot even hold a poster, let alone the curtain.
The hooks are made for thicker window frames, so they do not make good contact with the stickers.
In other words, I had to resort to using a hammer and nails.
The fabric is not of bad quality, but it easily wrinkles, leaving marks.
In short, it is quite inconvenient and the quality is mediocre.

It's worth 100%. Good quality construction, easy installation with double-sided tape included in the package! It doesn't provide complete darkness in the room (personally, I didn't want that)! Overall, value for money!

This particular one is only installed with double-sided tape. The package includes reusable tapes, but even if you use a better one, the surface is too small to hold its own weight. The plastic is of poor quality, resulting in screws breaking into pieces if you try to put them in.
