It's beautiful and an eye-catcher. However, it's unusable in the bedroom. I have no idea how people call this fan silent, especially when it's on the oscillation mode: There is a irritating noise, which for me makes it impossible to sleep with the fan on. I can sleep fine with a dyson or a cheap 40 CHF fan but not with the peter. There should be a fourth mode, sleep, which is weaker than level 1 because level 1 is already pretty strong.
Some decibel-values from my phone, taken about 20 cm above the fan: Level 1: 37-39 decibel. Level 2: 46-47 decibel. level 3: Around 55 decibel
