Product review (4 stars): Good, but you need to know its limitations.
I purchased this cooler 5 years ago , and after learning its limitations, I have to say this is a good device for the price. I am posting this review hoping that some of my observations will help new buyers avoid common  frustrations that I also expirienced when I first purchased it..
Cooler does brings the temperature down to 37F.  I had some issues with temperature staying between 45-50F. In all cases it was caused by frost on the back of the cooler. Once I took care of that, temp got down to 37F within 24 hours.
Frequent use or unintentionally leaving the door open for long time, will make ice appear quickly in my climat. I adjusted the way unit is leveled to ensure door always close quickly. My kids had bad habit of not closing it completely creating frost issue describing above.
Cooler needs air to flow between shelves to work properly. If you each shelve completely with cans it will have hard time bringing \temperature down.  If you put warm cans, leave some space open. Alternatively I buy cold cooler does not have to work super hard and with normal use, there is a quickly enough space in the cooler for air to circulate normally.
