Product review (1 stars): Buy cheap, expect cheap. You are better off buying a known Commercial Brand like True, Beverage Air etc.
Buy a True or  Beverage Air; do not buy this, you will be sorry. There is NO warranty service support. This is a product of the UK and would be fine over there where parts and service are available but in the US parts and service for these units are Impossible to come by. Do yourself a favor and trust me, I am in this industry, its cheap because its worth the price you pay for it, cheap.
