The distiller was easy to assemble, but I did need cheaters to read the teeny and somewhat blurring instructions. Also, although the listing is for a Mophorn brand, mine has a different brand name on it. The unit is pretty large, and the fan is pretty noisy, so we have it set up on a laundry room counter. I was so surprised that it made the first gallon in less than four hours! I did start with hot water, as recommended, so perhaps that sped it up.We have soft water, so there wasn't a lot of gunk at the bottom. But we absolutely need distilled water for the CPAP machine, as well as making soaps and lotions.I'm thrilled to have this so we don't need to make trips to the store for DW, nor lug the jugs into the house, nor throw them into a landfill when done. The heavy-duty glass container is a plus! It would be nice to have a timer on this, but for the price, I can't complain.Having only had this set up for one day now, I'll return to update my review if we run into any issues.
