Air75 v3 - are keys supposed to be different heights?
I just got a Nuphy Air75 v3 with the red switches, and so far it's been a fantastic little keyboard. I was experimenting with some shine-through keycaps, and noticed when I put them on that not all of the keys were a uniform height.
In the picture above, I tried to illustrate this with two different keys in the bottom row. I apologize for the poor photography, I hope the annotations do an OK job indicating what I am seeing a bit more clearly in-person.
When I put the new keycaps on, I noticed that some seemed to be more depressed than others, which was visible when viewing the keyboard's side profile. I thought I had perhaps pushed the caps on too hard (they were a tad tight on the stems). Taking the keys on and off and switching them around produced the same results, so I figured it wasn't that. I swapped back to the OEM keycaps, and same result (pictured). I then thought this was perhaps caused by uneven switches, so I swapped the switches between the keys pictured, and had the same result, so I figured it must be the board itself.
Is this normal? It's not something I've noticed on other keyboards, although admittedly I have not used too many of them and perhaps this is just the first time I am noticing what is otherwise a standard feature. It doesn't really impact the typing experience in a material way, so just trying to figure out if my board is just a bit warped (in which case I may try to exchange) or if this is completely normal.
Thanks for any help from those a bit more experienced!
