DIEWU USB3.0 2.5/3.5" HDD Dock

I bought this docking station to use my 4TB HDD as an external drive.
Because of the https://jiji.co.tz/172-fingerprint-scanners high capacity HDD, the old docking station did not see more than 2TB, so I ordered this one.
Packaging:

This docking station caught my attention with its built-in power supply.

There is no fan on the power supply, only a hole for it.

The power supply is quite modest, it doesn’t get very hot and works stably but not shielded, which is a minus. Even at this price, I did not expect.
The docking station is powered by a JMS578 controller

The computer recognized the controller immediately and opened the disk

The Android phone also opened the 4TB disk without any problems, as well as the TV opened the disk.

As far as disk cooling is concerned, almost nothing has been done.

For consolation, the case cover is easily removed so the disc can be cooled down a bit.
You can add a fan to the case, but this is something else.

Conclusion:
Good
-Cheap device
-Easily connects to a computer, phone, TV
-Built-in power supply
-Compact body

Bad
-The power supply is not shielded
-The cooling of the disk is bad
-The button to turn on the disk, badly solved, inconvenient
