I wish I had known that the opaque housing of the switches completely blocks the RGB light from the keyboard, but oh well, that's on me.
The switches are quiet and feel very comfortable to type on and they are probably the most satisfying switches I've ever used. I noticed a slightly plastic-y noise at the start that I wasn't a fan of, but it has either gone away or I've gotten used to it, but either way not factor any more.
If you're looking for a tactile switch that feels satisfying to click on without too much resistance or noise then you should consider checking these out

I love these switches. Exactly what I was looking for. Can now take my favourite keyboard to the office and type whilst on calls without people thinking they’re under machine gun fire. They feel so good when typing, more controlled and stable. Hard to explain, but it’s like they’re dampened without losing any of the tactile nature of the switch. Really recommend if you’re looking for a silent tactile switch that actually is silent and tactile.
