Four non-original legs for the bottom half of the notebook.
Original legs are less flexible. On gifs under the spoiler, I tried to convey the difference. Original on the second gif.
New legs, unlike the original, stood at the same level as the body. The photos under the spoiler can see it.
Another couple of photos.
The legs are made of tactilely pleasing materialhaving a smell, on the product page it is written that it is rubber. It serves its purpose better than the worn original. When installing the adhesive base, I warmed it up with a cigarette lighter for about five seconds, and the adhesive properties improved. The glued new leg looks reliably, it was not possible to unstick it with a small effort using a fingernail.
