I have a couple of the Mini PT3s. The tanks IMHO perform well. But there's no getting around the financial reality. The tanks are cheaper than the 2s for good reason. The heads are twice as expensive than the old single coil variety. Life's seemingly universal truth, pay now or pay later. Still enjoy them, though between the tank space lost to the taller coils and the burn rate I feel like I can drain one dry in 10 minutes vaping casually. : )
