An rda is a good thing for a vaper to have; for one thing, most rda's a very rugged/durable, so it's like a failsafe backup especially for when you regular device/devices has some silly problem you don't feel like dealing with at the time.
1: cool vape.
How cool vape a vape you get depends on your power source compared to the coil.
As for the coil, it's not only the ohms that matter, but also the wire gauge.
2: sub-ohm:
insulator materials are very important in tanks and drippers; it's important to have insulator material that will stand up to heat if such an event occurs.
Of course, anybody can describe a device as 'subohm' even if they have crappy insulators; just as a selling point; you can look up "peek" insulators.
3: adding juice:

most times you just remove the drip tip and drop/squirt juice down the hole.
Some rda's have a chuff cap, where you can take off just the top and get a good look at the inside without remove the whole topcap.
4: leaking.
leaking is an issue with rda's; they don't hold much to begin with, so most experienced rda users know how wet or dry their wick is anyway, and can often just vape off enough to ensure a dry enough wick that there is not a leak problem.
There are some interesting top-air-intake rda's such as the manta which are very leak resistant.
Thanks for the input. I landed on the Sapor, which is top airflow and should help with leaking. You're obviously knowledgable about RDA's, so I would really appreciate your response to my last post in this thread regarding safe RDA building/vaping.
Thanks for the input.
