Blackwidow elite vs Blackwidow V3 Pro - keys shaking/wabbly

Hi all, I just upgraded from the Blackwidow elite to the new Blackwidow V3 Pro and noticed that the keys have a different quality. For example every bigger key like space or enter is shaking and makes a very cheap sound compared to the other keys. I compared it to the Blackwidow elite and there is no such sound. Anyone with the same experiance or do I have a faulty keyboard? Thanks and regards Don
