Questions about Xiaomi Smart Air Purifier 4 Pro

Contrary to the positively expressed opinion of others, I find the noise that the part makes in night mode and level 1 really annoying, i.e. I hear the even clearly visible imbalance of the apparently only cheap plastic fan wheel - which possibly bends differently depending on temperature and humidity, which steel would not do so much and of course would also be more durable.ergo, it doesn't make a continuous sound, but a constant up and down--taken exactly, probably back and forth, Doppler effect and blaaa--with every rotation, is this the same with you--I'm only talking about level 1 and night mode, just to make it clear again, since somehow you always get answers to everything else here than you actually asked--? It's "quiet" in itself, but it's not a constant, unobtrusive, bearable sound, but rather an annoying "up and down" sound. Do you also notice this with your device, or do I have a model that I should possibly return? 0.o If I look at the edge of the fan wheel from above, I can even see how the thing is wobbling -- of course less than a millimetre, but still--, so I think that with today's industrialisation, you shouldn't be able to get fans that aren't perfectly round and unbalanced.So I just wanted to ask you quickly, do you also see this with your devices, how the edge always moves in and out a bit to match the annoying sound it makes at the slightest steps? Do you have to accept this on a "Pro" model nowadays? 0.o It doesn't do me --and the pollution-- any good to go through the whole return procedure and then get back a device that is exactly the same - or, as is so often the case, even shittier, if they were all like that... @Galaxus & @Digitec: For such cases it would be useful if you could post audio or video files here, so that others could compare it with their device, or that you can hear samples from others before you even buy a device! ;)
