Speedtest/review GL-MT300N-V2?

Hi, I’m searching a complete review of GL.iNET GL-MT300N-V2 router, I’d like to see speedtests with one and with a lot of devices connected and with/without wireguard (with 1 or more devices).
Approximately the quality of the wifi signal diminishes a lot at distances of 5-10 meters?
Are there any major bugs in the current firmware?

Thank you.
