An undercounter refrigerator can make the most out of your kitchen. This is because it uses up far less space than a regular refrigerator. At the same time, a downside is that these refrigerators are generally small. They still make a great convenience. Also, if you have back problems, be careful bending over to the undercounter refrigerator too much or with poor posture. This can exacerbate back problems. Other than this, an undercounter refrigerator can make a great supplementary addition to your home and works great in bars.
