I think it depends on what part of the country you grow in. Weed drys and cures different regardless if you're drying and curing it in a 60F 60RH room in both regions or not. For example, Colorado weed is always bone dry and the leaves just flake off which make it great for the Cannabrush.
Im in a very humid climate and I dry my bud for 14-16 days at 60RH and as close to 60F as I can get. The stems crack and buds dry to 58-62% humidity without the leaves being bone dry like that. They're pretty dry and kind of crumbly but it takes more effort than the Cannabrush to break them off so I always end up using my curved Chikamasa scissors to get the job done. The Cannabrush is useless in my region although I dont doubt it works well in other climates.
