i have never taken a sedans apart but there are generics and there are generics.. but the atomizers i gave taken apart the bridge is simply an extension of the rest of the wire wool that sticks up into the wool in the cart.. its there to make direct contact between one and the other..
the wet wool in the cart passes liquid via the bridge to the wire wool around the atomzer pot.. when things are all new and wet things work.. as the liquid in the cart wool gets used up things dont work so well..
to me its a technology problem.. the atomizers come from the factory loaded with a wet wire wool prime.. when a wet fresh cart is popped in its all at its wettest so to speak.. given a fresh off charge new battery things should work at their best..
the liquid in the wire wool gets pulled into the atomizer pot so its the wire wool that starts to dry out first.. the wire wool has to be fed (via the bridge) from the cart wool..
the overall wettness gets less as the cart gets used up.. the wire wool around the atomizer being the driest part of the lot.... in theory the overall wetness of both wire wool and cart wool should try and even out.. in practice i dont think this happens..
small carts seem to manage this balance better than large ones.. probably for the simple reason the liquid dosnt have so far to travel..
but as the cart gets used up the overall wetness gets less.. to a point where somewhere between functionality and none functionality is reached and the cart is changed for a new one..
one thing that is never replaced thow is the initial factory prime.. not unless two or
three drops of liquid in directly dripped into the atomizer before the new cart is installed..
i think the fluid used plays a big part in the passage of liquid from the cart wool to the wire wool.. thinner fluid is gonna equalize better than thicker stuff.. thinner fluid should work better than thicker fluid.. in theory at least.. he he
i have some pipes which i direct drip.. i have pulled the bridge off to directly expose the atomizer coil.. my theory was simple.. with no cart being used there was no need for the bridge.. it simply got in the way of my direct dripping..
i know thick fluid is bad news cos i have loads of the bloody stuff from e-cig china.. it dosnt even equalize in the carts.. there are patches of brown fluid and patches of pure white dry wool.. i think "hope" its connected to the olympics supply problems.. cos no way on gods planet would these thing work..
ruyan cigar fluid seem to be thinnish.. i aint tried the sedansa but the ruyan cigar is the only large sized cart
device that seems to work its way thru the contents of cart okay..
loong totem seem to have solved the liquid passage problem with a complete re-design.. the atomizer heater coil pokes straight up into the cart wool.. from people that have tried them the idea seems to work.. but the atomizer and cart are all in one..
so i think all the new super minies with very small carts will empty the carts as intended and work well.. but being as they hold bugger all in the first place and cost the same as the larger cart not a lot has been gained except a
device that work well but cost far more in new carts.. the same effect could be achieved by throwing a 901 cart away when its half empty.. the cost would be the same.. small carts are more idiot proof thow.. the user has no choice but to throw them away.. the lenghy period if "is this thing empty or not" has been removed..

ps.. i like generic classics.. but would never claim any off them work without dripping.. none of the ones i have tried have..
