I also want to mention that I use the Logitech G512 SE with the blue Kailh switches. My opinion is, is that they switches provide a meh tactile feedback. You feel it but I would like it to be a little more clicky. Especially if you are gaming and you are mashing the keys, they feel like browns or even reds sometimes. Since the PRO X is a hot-swappable keyboard I do suggest to buy after-market Kailhs like Box-Jades for a more tactile feedback, or sometimes the Kailh Speed Gold which are clicky switches with actuation point of 1.4mm and Kailh Speed Bronze with an actuation point of 1.1mm (only choose these if gaming performance is a priority but you still want click switches.)
