How often do you have to drip on that rda? What has the biggest well to not have to drip every 3 drags etc?
There are certainly lots of RDAs with large juice wells! Currently, I own a Magma RDA (which is a bit old school now...). If take off the top cap, coat my cotton with juice, and then fill up the juice well, I can puff on it for about 15 minutes! Honestly, the only people who are having to redrip every 3-4 drags are those that run very high wattage or people with older RDAs. Here are some other RDA's with deep juice wells. I will state that the Magma is likely the most noob friendly RDA, but here is a list of some newer designs:
Marquis RDA
Veritas RDA
The Big Dripper V2 (an authentic product that costs only $60! It has the steepest learning curve out of all these RDAs though.)
Doge V2 (more for clouds, but should be quite easy to build! By the authentic, it's cheap anyway lol)
Kennedy RDA (The authentic is a bit pricey, but I have yet to see reviews on the clones.)
I hope this helps put you in the right direction!
