Wow I am surprised they are still making these.
I bought mine back in 2018 and used them up until a couple of months ago.
The mouse eventually got too dirty, so I tossed it, but the keyboard is still going strong.
If you are looking for a simple wired LED Keyboard & Mouse combo, $20 is a solid value.

They aren't loud at all. These are not fancy mechanical keys so they don't have clicky sounds.
It's okay to use them in the office.

it says 2 pack, does that mean 1 mouse and 1 keyboard or 2 of each?

I paid 30 for the combo from NewEgg as well for mine. Only complaint is that turning off the lights makes the keys blacked out, as if unlabeled.

I don't know if this was changed, but on the old devastator keyboards, the RGB lighting on off was controlled with the scroll lock key. Which means it was near impossible to use this keyboard with Excel or anything else that needed to scroll, at least if you wanted it lit up. There are some fairly easy hacks and mods available to override this and keep it permanently lit, but you need to know how to strip wires or solder. The devastator keyboards aren't bad, they're membrane, but they feel decent and look good, and I always appreciate dedicated media keys. Not sure about the mouse, I gave it away. Reviews online say the mouse has some squeaking issues, again fixable, but for $20 for a mouse plus keyboard, you could do a whole lot worse.

The one I have that I bought in 2019 has its own key to cycle through the preset light patterns. It's the key to the left of the R-CTRL key. I've had worse mice that I paid more for.
I've had gaming mice that I consider dead once they do stuff like randomly dropping a L-Click Hold, which usually happens within a year. I don't do fast twitch stuff that requires changing dpi on the fly for sniping, so never appreciated that feature. I'm old enough to have experienced mice that lasted 5+ years.

Mouse is comfortable and I liked the keyboard better than my Corsair mechanical. For $20 this is an awesome deal if you need peripherals
