My Corsair rgb strafe is more quiet than a membrane keyboard. I did take off all the keys and put dampening rings on it though. I absolutely love it! I thought it was just going to be like that for a month until it breaks in, but nope!
I’m using a chinese mouse I got for $11 on amazon. It isn’t branded but it still has 4 buttons. Between that and the keyboard along with shift/control etc. More than enough.
