One of them would have to be the
SKU 9635984 as Essellar says. Great RDA.
The other one an original UD IGO-S because i've had this one since 2013 and it's still going on strong, still one of my favourite atomisers.
The 3rd would be an original A7 RDA - the tall one, with my DIY A7oid style drip tip converting it to Spheroid mode. The only tank i've ever had consistent service (at least, near to RDA levels of consistency) from.
Two old school AF, one modern squonker converted to top feed. I've been working on and off on making the Satmod 14500 clone from here work with 1 AA Eneloop for my use. Currently the lowest res i can get with my wire is 0.19 ohms and it isn't quite enough. Getting about 1100mah out of a 2450mah cell before output voltage drops too low. Eventually i will get some slightly lower res wire and get about 0.17 and then we will be in, i think.
