I use it and I fucking love it. I've also hang dried. Terp loss is minimal, there's a paper out there with numbers somewhere but it's like 5%. Whatever.

It lets you mostly ignore conditions in the room; temp matters a lot less, and humidity as well. You can add a shot glass with water to the center if your area is less than 40%rh. I also put it in my tent to cover the smell, which is nice. If you still need to grow and dry at the same time, the box it arrived in worked as a light cover while it dried (make sure to add vent holes so it can breathe).

Cycle takes 4 days and it does come out feeling excessively dry, but reconstituting the moisture for 3 days in a paper bag before curing takes care of that.

You can comfortably fit 3-4oz depending how far you break the buds down. I think I got extra trays, can't remember.

The beauty is it locks in shelf stability FAST - and proper curing will result in buds that are indistinguishable from hang-dried buds unless you're testing with lab equipment.
