i have the B3-23A 30 Plate Beer Wort Garden Hose Chiller from duda.. that thing does its job and then some.. i used to have a counterflow chiller and the exit water felt like it was in excess of 120 degrees, though the exit water of my duda is just warm and cools 5 gallons much faster.. i would say if you add on their hose barb options the barbs aren't very long though and i really had to wrench down my clamps on silicone to keep them from popping off.. a future upgrade would be for me to figure out how to fit sanitary fittings on there to keep the same as the rest of my hardware, can't go wrong with the duda quality though!
