one week have 2 keyboard broke, both also pcb or something issue with it.... causing the key cannot register or generating a bunch of random key on stroke.

Is it me or the quality of keyboards gone down the hill this recent years. Any recommendation on good quality and can use for long term keyboard?

I got a Razer Blackwidow this one suddenly happen cannot space bar, certain keys also register other words or multiple other keystroke. Plug and Unplug also cannot be safe.
Another is not a mechanical keyboard but a Microsoft Sculpt Comfort Keyboard. Same as my razer, suddenly the backspace key cannot function then the E key become 3 and the other key all mess up, pull out battery try plugging to other pc also same, gone case also.
