of course, like any other mod, i found some issues with it. someone did some tests on it and found the 510 connector would pull out, but another youtuber tried it and it didn't happen. they also tested something with the ohm reader on the mod, and said that was bad too, and that the sense blazer 200 didn't work with it, YET, other youtubers have said it's a great mod, and so have regular every day consumers. i have no idea who to trust here, should i just go for it OR should i get a smok h priv or a sigelei kaos? i have no clue. just need to make sure theres no overhang with the sense blazer 200 or sense blazer pro.
