Great first distiller. It works great and the residue rubs off pretty easily after a soak with vinegar/acid and water. The target/actual temp display is nice, but the actual temp seems a little inaccurate (or at least overconfident). You can see the actual temp value instantly drop a several degrees when the target temp is adjusted. No doubt that's why they suggest setting the target temp 5 degrees above boiling. Might make this system less suitable for distilling alcohol, but its no problem for water. Happy with my purchase, but if doing it again I would look for something bigger and faster. This takes roughly 3.5 hours to distill a gallon, so I've been setting a timer for 3 hours to avoid running it dry.
