I recently purchased an Aeolus RDA and at first, I thought the 510 heat sink adapter was stupid. But now I am finding myself using it separate from the Aeolus and with other mods and RDAs. I've thought of so many reasons for a good 510 to 510 adapter: wonky or partially broke 510 connectors where screwing and unscrewing atomizers is a task, it can minimize the "atty ring" left on mods, it might eliminate any gaps with certain set ups, or if you have a device without an adjustable pin, and 510 wear and tear since the adapter will stay screwed in. With that being said, it would be nice to have a selection of 510 to 510 adapters to use for this specific reason and not just heat dissipation or air flow, preferably with a lower profile than the Aeolus heat sink fins. Ideally, if a company like fat daddy vapes made 510 connections that simply screw in to the original 510. Might sound dumb, but I would definitely buy. Does anyone know of a good shop that might carry something like this? These are basically the only two types I found.
