Thx for the input. I'm actually circling around the NewVape grinders for about two years now, though rather considering the regular version – would they be too slippery to handle or why do you recommend the arm band version? How does it compare in size to the BCG (I'm actually looking for a smaller / not too big size as I'm grinding for my microdosing needs mostly).
I have the regular fine grind and traded a NV coarse grind (that I didn't use) with a member for the arm band version.
Why? Well, I'm 67, bit of arthritis starting in my hands, but mostly because I once tore my distal biceps tendon (it was repairs but..) and it turns out your bicep is not really for just curling things...its essential in twisting things (think door knobs, bottle caps, grinders! haha). So, I like the arm band version but the regular version is also outstanding.
The outside diameter of the NV grinders is much bigger (its a heavy chunk of metal) but I do think the interior grinding area is the same size...eh, maybe somewhat bigger but not noticeably big...
I do wish for a bigger BCG as I do find it somewhat tough to grip at times that I load it up well with some good sticky bud.
Micro-dosing...I don't do this so have little experince to share. But, the NV grinder must be dumped out on something as its a two piece. I did...and still do...kind of bulk grind (think an eighth at a time) and then pack into a Space Case or similar. So, I don't mind a two piece.
The BCG grinds into a dish at the bottom as its a three piece which may suit you better as you can grind and then just use out of the dish what you want, close it up, and then go back into it for your next session.
Both are very good devices, IMO.
