Good product for the price. It looks sturdy. You will only need some screws to connect the front section under the seat.

Good price (12 euros), iron rack with a total weight of one kilogram +/- 40 grams (for any combination - for V-brakes but also for vintage bikes), with expected pros and cons. Among the pros, it is relatively easy to adjust to whatever mounting combination suits each person. Also among the pros are the safety nuts. Among the cons, a screw was missing for complete initial installation (although there were two extra safety nuts). This can be easily resolved with a screw from a bottle holder base. Also, it is completely crooked on its right side. That is, three-quarters of the rack protrude to the right side. Among its positives, the small rack with the strong springs that it has on top of the rack. And as expected, it is painted after the basic assembly which means that if you move the small rack a little to the right or left, along with the springs underneath, it is UNPAINTED! It is acceptable, relatively speaking. According to M-Wave, it can hold up to twenty kilograms and I have no doubt about that. Also among its pros is that it has a "bumper" on the back with holes for universal night light installation. In the video I provide, someone else also mentions that it was crooked, protruding to the right side when he installed it, but he did not show how he straightened it. https://www.youtube.com/watch?v=8aMC5aDQh7s&t=98s
