Noticed an ad in High Times for this trimming tool. It's a tub with a 150 micron screen. In another tub. They say it's for trimming bud by hand and as your trimming the keef falls through. But my thoughts are - when your trimming bud it's wet off the plant so I wouldn't think the trichromes would be brittle enough to fall off and fall through the screen. Has anyone used this? Or what's yall's thoughts?
