Now you have to worry about the flight characteristics of your platter!  😀

This is nothing new.

It's a lifestyle turntable that looks cool, but it's not a hi-fi product.

FWIW Dept.: the coupling between the platter surface and the base of the tonearm is one of the more important engineering aspects of a turntable. If they are not tightly coupled (and also as dead as possible) then the arm can move in a different plane as opposed to the platter surface. This will allow the arm to interpret that motion as a coloration or sound.
