I used to have one when I lived in an apartment. Very happy with it. Only got rid of it because I moved and had built a proper cellar.
Do you have any specific questions/concerns?
I was really happy with mine. It's whisper quiet, barely uses any electricity and is about as big as you can get. Obviously not the most anaesthetically pleasing fridge, but not too ugly either. Realistically, you're not going to get the stated number of bottles in. That number assumes all standard sized Bordeaux bottles.
The only downside (and really would apply to any fridge of this style) is accessibility. When almost full and you want that bottle that happens to be towards the bottom on the back, you need to pull out a lot of bottles to get to it. So pack is strategically and use something like

They seem to retain their value too. When I no longer needed mine, I managed to sell it for about 65% of what I paid for it.
