good model, done well
25 October 2025 
It's great, it's enough for the shvidka, but the design has a little thoughtlessness.
Good speed, long USB cable, adapters for different sockets, strict laconic design.
The casing feels very fragile considering the mass of the hard drive, and it probably won't survive a fall from a desk. It lacks rubber feet on the larger side to place the drive horizontally, so a mouse pad needs to be used to dampen the vibrations that transfer to the desk. When set up as intended by the manufacturer (on the rubber feet on the smaller side), the drive stands unstably and could easily fall over.
