Okay, so I finally caved and bought the AULA F75 after seeing it everywhere online. And wow, this thing is LEGIT for the price.
First off - the sound? *chef's kiss* It's got that perfect creamy thock right out of the box. I catch myself typing nonsense just to hear it sometimes. The pre-lubed switches make such a difference compared to my old cheap keyboard.
The RGB is actually really nice - super bright with tons of effects. I mostly keep it on a single color though because I'm boring like that. The knob is super handy for adjusting brightness/volume.
Battery life has been insane for me. I've been using it for work (lots of typing) and some gaming for over a week without charging. And that's with the RGB on about 50% brightness.
Only minor complaints: The software is kinda trash (but I don't really use it) and the switches are SUPER sensitive. Like, I've accidentally sent half-written messages because I rest my hands on the keys. Might swap them out eventually since it's hot-swappable.
For the price? 10/10 would recommend. It feels way more premium than it should at this cost.
