So, I've been rocking clearos since day 1, as the peeps at the store I shop at always push them as the best juice delivery device on the market. They have a dusty shelf in the corner with a few cartomizers and carto tanks on it, but I never really paid any attention to it. Lately I've been reading more and more about DCT's, and a lot of people seem to prefer cartos to clearos, so I thought I'd give it a shot. Went to the shop and lucky me, they are on clearance for 5 bucks for a dual coil carto with a 6 ml tank. Bought 1, went out to my car, filled it, let the juice soak in for a few minutes, and then took a puff. A BIG puff. Made my windshield disappear. Long story short, went back in and cleared that dusty shelf right off and added another 6 carto tanks to my collection. They are fantastic. Great flavor, nice throat hit, huge clouds of vapor. I wish I would have tried one of these earlier on. I've got at least 50 assorted clearos at home and a shoebox full of spare parts. I honestly don't know if I'll ever use a clearo again. DCT is the way!!! I've been converted. The only problem I foresee is that changing flavors will essentially mean changing cartos as I can't see how one could clean the filler out completely. Other than that, these seem to be superior devices as far as I'm concerned
