Firstly, keep your battery wraps intact and don't overstress your batts (aka by over-discharging them or putting overly low resistance builds on them). Respect your cells as they're pretty much cylindrical C4 sticks if you misuse them.
Just keep in mind Ohm's law and vape to the amperage limits of your batteries (the REAL limits, not the bogus limits some rewrappers like to stick on their batteries) and you should be fine. Also, 510 pins (flush = death), but that only applies to hybrid 510s (which is why I don't really prefer to recommend mechs with those IMHO, but nowadays most Mechs come ONLY with hybrid 510s so there's not much of a choice).
TBH, I ADVed a whole bunch of Mechs (and a Taifun GT) for the better part of 2 years and I STILL have all my fingers so it's not THAT dangerous really. You just need to be aware of the risks, is all.
Alright thanks sifus. My vgod rdta just came. Coil it using fused Clapton x 2, and put into my regulated box mod, it shows check atomizer. Tried it again using kanthal a1 24 6 wraps, shows check atomizer warning message again. Haiz... Don't know what the issue..
i gotta admit when i first used Merlin Mini, it did leak and sometimes faucet like lol but i'll try find time for a short video or at least a pictorial on how to seal off the wicking hole on Merlin deck to prevent leakage which its really effective. -thanks to a kwailou in Vaping Underground
