It works, not sure why it has a glass door. I have a temp gauge inside and the temp has held steady. There is no gauge included so you are expected to guess the appropriate setting. I haven't had it long enough to give it an accurate assessment. The three standard bottles I have put in it have all fit with no issue. It is compact and pleasing enough to look at. It looks like the door hinge can be reversed, although nothing is mentioned in the manual. The longer it lasts, the better the value.
