This was recommended to me by a family friend that uses it to make his own hash. I gotta say it's really easy to use and is definitely worth the 30 bucks. I've used it several times, its sturdy and has great material quality. It does its job perfectly I use it and cycle twice per batch and get a great amount of "herbs". I recommend giving this item a try.

After 4 runs the 5 gallon bags held up and do make quality dry ice and ice water (bubble). YouTube videos/ internet forums have easy to follow instructions. Very simple easy to use for smaller home growers
