@starr I would tend to agree on the potency part of your post ,I used
TrimPro's and Twister's a couple of years ago,We did side by side comparisons with hand trimmed nugs and no one could tell any difference on potency,though everyone could tell their was definitely reduced aroma and flavor on the machine trim flowers.....especially after a nice long cure
So we're back to hand trimming here,since that's what produces the highest quality product for us,and yes we have professional trimmers who do excellent, quality work.....poor hand trimming is not any better than a machine,but professionally hand trimmed, manicured nugs always provides the loudest, tastiest product for us....
