Adapters can be the cause to shorting out an atty so they are not the always passive device you seem to make them out to be....ask Isaac.

I had a 801 to 510 adapter for a year on my original REO with never an issue. That being said it was an adapter that was sold by many suppliers.
Oh my goodness - I'm learning all kinds of stuff. I'll not try an adapter any time soon to be on the safe side. Maybe I'll get a 306 along with a Cisco 510. Thanks for info about dewicking & the ohms. I didn't know that.
As we can all see, here is the result of one post stating that adapters will short out your PV and ruin it. I know of 40+ plus vapers who use adapters with no problems and there are probably thousands+ that use them with no problems. The end result is that you are telling people the only atty/carto that you can use is the 510 since they make up the majority of the connectors. I would bet that the person who started this has never vaped on anything but a 510 and incorrectly thinks it is the best atomizer on the market.
I guess all other atomizers should be discontinued.
