Unit is crystal clear clean inside only used with distilled water ever .Has hot and cold mechanism Very nice NOT a upside down bottle unit . Has 1/4" pex line for easiest installation ever .Very nice but the exterior could use a magic eraser cleaning . And the top has a stain on it . Someone used it as a table . Theres no damage at all and could be painted or left as is 2 buttons hot and coldVey nice .Shipping will be no problem just keep upright for 24 hours after receiving it so the coolant settles .ChillerHeaterDrinking water serving unit is top of the line quality and compliments my distillery unit i have listed or any other systems including tap water .Good to go packaged nicely first good offer gets it . Dont wait .Way underpriced !
