I almost exclusively use my GR8TR Vape now that I have a fine and coarse plate. I used a small 4 pc Space Case Ti for 3 years solid (during my combustion days) before I got my GR8TR. The Space Case is all but relegated to being a sifting device when I fancy some kief.@Winegums, what grinder(s) do you use?
Like Ramahs said, it's very consistent no matter how little or much you put in. Just gently twist applying a tiny amount of pressure. it's almost magical how it pulls apart a nug if you do a slight twist then take a peek. I've done this a few times to observe how the tooth design is working. The teeth act like picks that pull at first then start to cut as they reach the point that they can mesh. It was awesome to discover that the design has two distinct mechanical actions that includes a transitional phase. Most grinders are single phase interlocked teeth that are always meshed. It's a very well sorted and engineered design that isn't really replicated anywhere else on the market.
I honestly don't like Kannastor for their poor support of this design but love it so much that I can't help but rave about it.
