Denoch there is in my opinion no alternative to this fridge if you want to operate the device in the 1 bedroom apartment and also sleep.
30dB are very quiet, you can hear whispering only the fan and is thus not disturbed in his sleep.
On medium setting the unit to 5.5 degrees cools which is sufficient and at a room temperature of 23 degrees!
I would buy the device anyway again and therefore give 4 stars (have flat power :-).
