Product review (5 stars): I ordered the wrong set - excellent return service
I didn't do my research properly and bought the set with the couplers for commercial kegs and not the ones used bu home brewers.  I phoned the Beverage Factory and they were very accommodating and would let me return any unwanted part for a refund and order the parts that I needed.  I am now waiting for the parts to arrive so I can build my two keg fridge with stainless steel tower and two taps.
