i still don't get what it really means? i saw the examples cited above and they either are bridged or bridgeless design but i can't see enough to tell the difference visually. i sure don't plan on chucking this .357 for a long time. don't know if it is bridged or bridgeless.
The bridged one has stainless mesh over the coil to act like a wick. The bridgeless one has the coil in a ceramic cup.
Both work the same way. Screw it on to you PV and drip 3 to 5 drops into the atomizer. This can be done through the drip tip if it has a wide enough opening, otherwise you will need to pull the drip tip off to drip your juice onto the coil. BTW this is how drip tips got their name.
You vape until the juice is almost gone the drip some more.
The bridgeless attys are IMO the easiest to clean, usually hot water is sufficient to remove residual taste. With bridged attys I use baking soda and vinegar to clean them before next use.
