It has been 4 years without any problems and it continues to do what it promises without ever letting me down.

Although I haven't tried the clone disk yet, it reads all the disks I have inserted at excellent speeds. I will come back for the clone disk in the future.

It supports 2.5" and 3.5" SATA I/II/III HDD / SSD.
The most important thing is that it accepts unlimited disk capacity.

2 years and still working flawlessly with transfer speeds between PC/dock with a regular HDD in the dock up to 170 MB/s consistently.

Quite good. I noticed some difficulties in operation when it is connected to power, so it would be good in Windows to first remove it from the systray when shutting down the system and then turn off the computer.
When it is not connected to power, it works perfectly. Its speed is satisfactory

After 2 years of smooth operation, two hard drives from a reliable company broke down. I had to restore files and luckily managed to recover my data. It's a shame

Quite good and helpful little machine...
It can read both disks simultaneously, the speed from one disk to the other (when you have 2 hard drives in the Box) is 19.5-20.5 MB/s, while from the computer to the Box (and vice versa) it is 39.5-40.5 MB/s. For 45€, it's perfect and does everything, if you don't have high speed requirements (meaning you don't use it for professional purposes), you can choose it without hesitation.

Update: 21/1/2021
It's time to clone (without a computer), the speed is frustrating... from ssd250G to ssd1T it took 4 hours and 45 minutes, the result is negative, it is not recognized by the computer. When the hard drive or ssd doesn't have an operating system (meaning file transfer between disks), although the speed is slow, the result is positive.
I will continue testing with ssd and hard drives and will update

A major problem with the Station is that despite its USB 3.0 connection, the file transfer speed is about half of what is expected. Other than that, it does its job.

Quality construction and great ease of inserting old disks and taking extra manual backups without any problems so far. (I haven't tried the clone). The small USB cable didn't bother me because I have it on another USB hub. Be careful when inserting a second disk while there is already one inside, as it resets and it's like abruptly removing the first one!

Very good! It copies both hard drives, whether they are SSD or regular, perfectly and quickly, whether they are operating system or data, without being connected to the PC.
