The deal changed to Red Switch model.
Red switches are linear, in that they have no tactile bumps. Linear switches are said to be quieter than other switches (Tactile or clicky), but they still make a lot of noise if you press the keys hard. Plastic hits plastic as you hit the bottom, the noise then gets amplified with the keycaps and the keyboard body.
If you want a mechanical keyboard that's quiet for office and such, this one probably isn't one. I personally recommend switches that have silicone dampeners in them (like Cherry MX Silent Red, Black, and more) or a decent membrane keyboard instead.
It is referred to as "Low Profile". In terms of the height, while it is considerably shorter than "full-size switches", my understanding is that if you compare it to other low profile switches (say Kailh Choc), it's fairly tall.
The "go to deal" button goes to a $69 one. Found the cheaper one here https://www.amazon.com.au/dp/B0856W4MSR/ref=cm_sw_r_apan_glt…
