Long time reader, first time poster.
I received the Xike managed switch mentioned in the OP yesterday. Was 82 USD shipped after various Aliexpress deals. The package it arrived in was small enough to fit in a standard US mailbox.
The web UI is horrible to use, it is so slow every click takes 15 to 20 seconds to respond, if it doesn't time out.
There is a
web user manual in Chinese that walks through every screen of the web ui configuration in detail with descriptions and can be translated by Google Translate. The device itself comes with basic printed documentation in Chinese only. Web UI on the device is in both Chinese and English.
Config options are extremely basic. No https, no telnet or SSH CLI access, no SNMP, no configuration of link aggregation or spanning tree protocols other than off/on, etc. No apparent way to define a port as a VLAN trunk port? (but maybe I don't know what I'm doing/don't know how to interpret the UI options.)
As a dumb switch it works, I haven't figured out how to do the vlan config properly to say how that works yet.
Settings changes take effect immediately but do not persist after a reboot unless you click save on the tools menu. That way you don't make a mistake that will lock you out.
On the plus side it is cheap, small, silent, and runs cool to the touch.
