1.0ohm SLR Cisco Spec 306 Bridgeless Atomizer (Open center post)
These are standard Cisco Spec SLR (Super Low Resistance) atomizers with absence of a bridge and its wicking material creating an exposed coil. These will work on any 510 connector including bottom feeders as the center post is open.
These atomizers are custom designed with a very low resistance coil (1.0ohms) and create thicker and more flavorful vapor on VV/VW Devices and mechanical mods that use single cell Lithium 3.7v batteries ( do not use above 4.2v or on dual cell devices). These atomizers are not designed to be run on standard (cigarette sized) or non-vv/vw eGo batteries.
These atomizers are for dripping only and require a drip tip or juice feed system, cartridges will not feed juice to the coil with the absence of a bridge. There is little to no primer fluid used in manufacturing of these atomizers, please drip 4-5 drops of e-liquid on any new atomizer, give the liquid 30 seconds or so to soak in and wet the coil, drop another 2-3 drops just before vaping, take a cold pull and listen for a slight gurgling sound, if not add a drop or two more and test again. Do not run the atomizers dry as this puts excess stress on the coil and could permanently damage the coil.
There is a learning curve inherent with SLR atomizers and you need to understand how to use them properly and not damage them. I don't recommend these atomizers for users who are new to vaping unless they understand the proper use. There is no warranty on these atomizers and are guaranteed to not be DOA.
