I have other items like it, but life is hectic, busy and who has time to mess around with something that you need to babysit for hours on end. I added a cheap timer, 3 hours and it’s done. Set it to 95 degrees Celsius that’s it. Done and done! Oh, my advice, Pour it all through a zero water filter afterwards, add some distilled water and glycerin to your liking, and just have fun with it. There’s so many ways to flavor, candy, wood chips, fruits the list is endless! No regrets wish I had another!
