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 old bicycles), with expected pros and cons. In the pros, relatively easy to adapt to any mounting combination that suits everyone.
Also, the safety clips are a plus.
In the cons, it was missing a screw for a complete initial installation (although there were two safety clips available). This can be easily solved with a screw from a bottle holder.
Also, it is completely crooked on its right side. That is, three-quarters of the rack protrude towards the right side.
In its positives, the rack with the strong springs it has on top. And as expected, it is painted after the basic assembly, which means that if you move the rack a little to the right or left along with the springs underneath, it is UNPAINTED!
It is good and tolerable, relatively speaking. According to M-Wave, it can withstand up to twenty kilograms and I have no doubt about that.
Also, a plus is that it has a "guard" on the back with holes for mounting a universal night light.
