Update - after lightly sanding the top and bottom edges of the handle, it now sits inside the groves when the handle and the thin metal bands sit to hold the glass collection picture. I ran one full gallon through the distiller and it worked fine, and as advertised it does take a few hours. The max fill line was slightly excessive as it comes very close to overfilling the collection picture, so on my next batch I'll drop the fill level 1/4" to insure no issues.First note, this is massive in height. Have not plugged it in yet, as the handle is to large for the collection picture, although I believe I can modify it to fit? The heater has an attached power cord that plugs into the base, and it's dedicated (keyed) so you can't plug the incorrect cord into the wrong hole. Aside from the included powder (?) I can't imagine anyone needing directions.
