have you tried checking of OCC not screwed properly to the base?

ive seen defective m65 models on internet cant fire on certain watt

Im using subtank mini as well and got the same thing, turns out its no issue. If you're going sub ohm, you will need a certain watt to fire it. Ur case the, the baseline is 15 watt to get it going.

mine also abit sot sot oledi... fully charged but after few hits it says batt weak... unit less than 2 weeks old...

In term of safety and batt life, yup. Since there is no more new Sony batt LG HE2 and LG HE4 is gaining a lot if love recently.

beside the LG, sony VTC4 also nice. Not really overkill since its 30A but it can last loong for years

the top 1 v2, the btm v1...

i google it and apparently theres this connection issue between the batt and bottom cover... followed the instruction by sandpaper the connection point and my unit is working good as new...

I am a frequent customer of theirs since they bring in a lot of imported juices. A few months back their service was great, but lately it got from bad to worse, the new staff they hired couldn't give two shiets about attending to you, sometimes busy with their handphones or their own vapes. Sombong. The owner also macam x minat to layan the customers most of the time, just let his staff do it.

They do however give me some discounts at time, maybe 'success' has gotten to them. Now i purchase from LeGadgets due to the friendly customer service i receive although they have NEVER given any discounts despite me buying hundreds worth of juices.

So far my new fav is Vape Empire, i get quite a lot of discounts whenever i go.

most driptips work out find on subtank mini or most tank ....

most drip tip is compatible .. if cant fit mostly because its oring only .. no issue .. just lubricate it and all ok ..

back in the days .. pinoy drip tips is hard to fit because its large oring ..
