Well, it may not be too easy, I mean there are risks that have been mentioned before. It seems that every now and then a 6 to 10 dollar atomizer can be suddenly ruined trying to remove materials that were included in the price we paid. Also, they would cost so much less, because of the missing manufacturing processes, and the bridge assembly components too. I think most people would buy both kinds, at least I would. Sometimes I do like to know I have 3 to 6 drops available in the filler cartridge, as well as 3 in the atomizer, but sometimes I really need them without a bridge and at a lower cost.
