Product review (4 stars): Unit is not Cooling Properly - Resolved
I am experiencing the same issue as some other recent reviews with the unit not cooling properly.  The beer exiting the tap is coming out at 46.5 degrees F and is causing excessive foaming, despite efforts to regulate the C02 pressure.  I just sent a note to service@smartplusproducts.com and will advise in a later post if they help resolve this issue.
*Follow Up - The company did contact me in a timely fashion and sent me a replacement refrigeration unit.  This is now cooling properly and I am satisfied with the product.
