never heard of it until you just asked. I looked it up a little on the web. Apparently it runs around $500. $600 with shipping. Looks like it will dry your bud in about 3-4 days. I can dry my bud simply by hanging it, in about 5-6 days. Seems like a huge waste of money IMO. They do sell herb dryers that are cheaper, around $170. Still a waste IMO.
