“after using it for a few days, I have not been able to get used to the low profile combination with Nuphy Keys. I also think the Nuphy is not worth 139.99 or more depending on switch options.”— EspadaDeDios on Reddit

“The air75v2 still has issues a year and a half into its launch. Unless I use a custom firmware the dongle and bluetooth performance is ass. It spams keys constantly when pressed leading to frequent disconnections.”— dotted_and_secured on Reddit

“My Air75v2 was also my first mechanical keyboard and yes, even with Wisterias I had to re-learn how to type, now using too little force. Like after a month later, I stopped misstyping. So, just give it some time.”— lcsolano on Reddit
“Just received my Air75v2 at work earlier, and had that same wobble. I can confirm that the base is bent, since I checked mine against a calibrated granite surface plate we had at work.”— Tenchi_M on Reddit
“I have the NuPhy Air75 V2 keyboard and using 2.4 wireless + MacOS. It has the odd duplicate pressing sporadically problem. On wired it works flawlessly though.”— slootz on Reddit
