As a seltzer loving family, SHAOHONG makes a lot of sense (economically) for us versus buying seltzer. I'm not sure about SHAOHONG versus competitors, but when it comes to SHAOHONG, this "WT-18CS" model was the second best; the "Source" model is the best I've tried. All SHAOHONG systems are ridiculously simple which packaging is great: it's just plain cardboard, and going from box to drinking is no more than 50 minutes. The design is also good, and fits in my counter perfectly.• countertop, cold water and soda water (double function) • Pure copper spiral evaporator, compressor refrigeration • Smart temperature control,dispensing -8℃ cold/soda water continuously • Cold tank capacity is 4L, Soda water capacity is 1L, tank material is SUS304 • The CO2 bottle can be installed either internally or externally • POU version, built-in 1 or 2 filters • Stainless steel shell design, elegant appearance, high-class look, easy cleaning • Compact size, suitable to place in the living room, kitchen, meeting room, office and other places ◎ Container loading: 1×20ft Container: 448 pcs 1×40ft Container: 868 pcs 1×40HQ Container: 1085 pcs
