This little countertop distiller is an inexpensive alternative to buying distilled water at the grocery store. So far, I have produced about 10 gallons of distilled water and it performs as advertised. I have an ice machine of the same brand that is now 3 years old, so hoping this distiller will last as well. The drawbacks are these: First, the operator's manual lacks a lot for clarity. Secondly, either the machine or bottle are not to dimensional tolerances, so that when the receptor nozzle is on the bottle it is slightly higher than the dispenser nozzle on the distiller, causing the head of the distiller to be slightly cocked and compromising the seal between the head and body of the distiller. I solved this problem by taping some pennies on the feet of the distiller to make it slightly higher.
