I bought a Nova when they first came out. I like mine, but I'm a gadget guy. I am a chronic user, so I find I must ingest a large amount of THC to feel anything. I decarb concentrate with the Nova, and dilute with Everclear for tincture, or drawn butter or coconut oil to combine w/melted chocolate for treats, etc. I put the concentrate in a shot glass and place it in the Nova. Legal concentrate in my state has THC values listed, so it's easy to figure out THC/dose. For example, if concentrate is 80% THC, then in one gram there are 800 mg of THC. Add enough alcohol or oil to make an ounce. In one liquid ounce there are approx. 590 drops. So each drop contains 1.35 mg THC. I often (not always) add a gram of liquid sunflower lecithin prior to decarb.
