Pure disappointment.
1st problem, as the friend Theodoros0123 wrote below, the synthetic cover for the LED lights sticks over the point where the screws hold in the box that functions as a drawer. In other words, you peel it off (and then what do you do? Do you use UHU to put it back on?) and if it doesn't break, that's good.
2nd, my package didn't have the screws and the rubber band to hold the NVMe, making it useless for me. There was no review from the friend back then, and I wrongly assumed that they were not included since the manual in the package and the product page did not show them in the contents, only the cables, just as I found them when I opened it. Unfortunately, I neglected to send it back and ended up with a useless case since it only screws in to secure and function.

Waste of money! I have had it for about two years, instead of a screw it has a rubber band to hold the m2 in place. Obviously, after so many years, I decided to upgrade my setup and put in a larger hard drive. The geniuses who designed the case made it consist of two parts, a casing and an interior (like a little drawer) where the m2 attaches. The problem is that the screws that secure the drawer to the casing are located behind the plastic that attaches to the LEDs (it's a transparent adhesive glass). So if you want to change the disk, you have to detach it and because it's hard, the glass will definitely break. Lastly, I would like to add that I encountered several random disconnections during these two years.

Very good, easy to use, and with high speeds. It heats up as expected for a disk.

Update
When I used it with real data to take a backup, I realized that I got myself into trouble. The speeds it reaches are from 20-100MB/s.. it's better to get an SD card if you simply want it for backup. I searched for a firmware update, but there is nothing on the site. I sent an email to the supposed support, but there is nothing.

My setup:
LC case + Samsung 970 m2 500GB, connected to a USB-C with a speed of 10000M, reaches 20MB/s. When connected to a USB-A with a speed of 5000M, it reaches 100MB/s.

Black dog, comes with two cables, a USB to type c and a type-c to type c cable. It also has the option to hide the RGB. It simply does what it's supposed to do and does it very well.
