Product review (4 stars): How to adjust your beverage cooler
I purchased this beverage cooler with doubts in the begining, but once I received it I was pleased with how this unit was well protected. For those of you stating this unit will not cool lower then 39 degrees, I hate to inform you, but it actually will. I say this because I have manually adjusted the thermostat down to 33 degrees, I can go lower but I rather drink my beer then chew it. I will explain this process shortly, but to give you another example I called the support line regarding this cooler and just as I expected I was also informed it would not cool lower then 39 degrees. From previous post that I have read I saw a number of people stating it is adjustable...YES... it can be adjusted, and just in case you missed these posts, you have mine to read. This is how. 1st once you receive this unit please allow at least 12 hrs for it to run within the middle setting. After the 12 hrs locate a small flat head screwdriver and place it under the turn dial of the thermostat. With just a little force pull the knob with the help of the screwdriver and this dial should pull off completely. 2nd notice the small Phillips screw to the left of this dial, this is what you will be adjusting until you reach your desired temp. To give you an example, I set mine to start cooling when it reaches 39 degrees and to stop cooling at 33.5 degrees.  (It can be done, just patience Daniel son)...The small Phillips screw will need to be turned clock wise a few rotations. Its best to turn 1 full rotation and allow the beverage cooler time to set the new adjustment. Continue this process until you have your desired temp, than place the turn dial back on and this is what you will be using to tweak your adjustments from now on. I hope this helps and the reason I didn't rate this as a 5 is because the wire racks are crap! Go to a glass shop and have your shelf's cut. Besides its a classier look. The blue light reflects nice with the glass.
Thanks and Cheers!
