What is the opinion of Reddit about the
Logitech Compact Keyboard K300 (Black)?

This one? Been using this among others for about 6 years now. Still works great.

I type like 115 WPM both on my "crappy" $30 Logitech keyboard and on a mechanical. I don’t think your experience is necessarily the norm.

I had this thing for like 5 years now and its still works perfectly.
