This has probably been one of the better setups so far in my Boreas and RDA's. But it does in deed require some giddyup to get them going initially. But once warmed up they will chuck some thick, warm, and flavorful clouds. I usually run around 70-80 watts, but will go up to 100+ on occasion for giggles.dual fused clapton will give u some thick clouds also but needs allot more power to heat up
