Being thermoelectric, it will cool the contents by a certain amount below ambient temperature. In our space, it is pretty close to the specified inside temperature of 5degC. I measure 8degC (46degF) for the beverages inside, which is about 30degF (17degC) below our ambient room temperature. While it can’t get as cold as something operating on a refrigeration cycle with a condenser and evaporator, it is quite close. For example, my full size refrigerator operates at about 34degF (1degC). I find that this mini fridge keeps drinks at a refreshing temperature. No, you can’t adjust the temperature, but that is just a caveat of thermoelectric heating/cooling.
Being small in size, it does take a while to do the initial cooling. If you were to take this fridge on a road trip, to use as a cooler, I would recommend pre-chilling what you plan to put in it. When you remove a drink and add another, it is much quicker to cool down the replacement because of the thermal heat capacity of the other contents and conductive cooling from them.
Something that I like about the design is the latching door, which makes it easy to carry without worry about things falling out. The handle on top and optional DC power also add to its portability. I also like how quiet it is when operating, not much above ambient room noise. It is clean and modern looking with its glass front panel and stainless steel appearance. I find that the squared shape makes it fit nicely in many spaces, while maximizing inside space. It is quite economical to run, only using about 80kWh to operate for a year, which equates to about $7 where I live.
I am unlikely to use it for heating, but it is nice to have that option if I ever need it. It would be handy to bring to an event to keep appetizers warm.
Overall, I’m pleased with the performance of this mini fridge. It meets with my expectations of what the specs say it can achieve. If you understand the limitations of the thermoelectric design, I think you will be happy with it.
