I think that the wobble came in after opening the switches, not strictly related to the lubing.

I tested some before opening them and didn't notice any wobble. The other keyboard mounts Drop Holy Panda X and I didn't need to film them at all. They were solid as a rock once closed after lubing.

I admit that I don't know the exact specification of the two, but from a direct typing comparison, I feel a bit faster on the Panda X keyboard

Unfortunately I didn't have a chance to directly compare U4T to U4TX, but I have another keyboard with Holy Panda X and here is my thoughts.

I first tried some stock switches (no lube, no film) and while the sound was already thock, the typing feeling was not as much satisfying, the switch response was worse than Panda X switches, so I definitely wanted to lube them.

Before opening the switch, the wobble is not that noticeable, but after lubing the wobble is definitely there, so I filmed them all.

The final result after lubing and filming is the most satisfying typing sound I've ever had, a nice fat and thock clack for every strike and the typing experience was drastically better.

Being 100% honest, currently I still prefer a bit more the Panda X as they feel faster in the switch response and offer a smoother typing to me, but it could also be a matter of habit
