It's very small. I understand that it's supposed to be, but it's too small. If you have bottles that are not slim you can't fit 20 bottles in it at all. It needs to be a bit wider and taller and it would be great. I had to take out a shelf and lay bottles on top of each other in order to get 20 bottles in it. I can say that it's pretty quiet and seems to be working fine so far.
