I've been using cannabis medically for over 10 years, always had problems using the rosin my son made for patients but hated the whole torch ordeal.
Until I discovered these I would smear it all over the sides of other coils, just gave up.
These are wide enough for a twitchy old broad to have no problems with- just smear it on and put the cover on.
The taste is so clean and it lasts for a looooong time- no harsh feeling and such a nice taste.
Great coil and I highly recommend it- as well as the seller.
