Anyone out there buy, or try the new bubble hash machine? Am trying to figure out if worth the cost, and how the yield is. Right now, and am not sure why its hit, and miss for me in 5 gallon buckets. Sometimes I have gotton up to 17 grams, others am lucky to get five, its very inconsistent. I've seen video on them on UTUBE, but would like to know if anyone has personal experience w/them. Thanks Much!!!
