I forgot, one more thing, I have dropped my subox 3 times, and have had it fall over when I sat it on the counter and it hits hard, as because it's heavy...so far it's still working... I've been afraid each time that it's not gonna work, but has so far each time, even though I know it's not good for it... Can it pop a coil if dropped to much? And I'm afraid to ask what could happen to the internal parts, it's hit hard enough, that when it was dropped the battery cover and battery came out....so far seems OK. Although this time it seems like the vape hits are not as strong, do you think something happened to the coil? I have only had this setup for a month now, I started in September with a vape pen, then each time went up a little step, although a few times I was taken advantage of because of my lack of knowledge, and purchased upon the shops advice only to have gotten something completely worthless, that happened twice and I'm a person that can't afford to pay for items just for the heck of it... I spent a 100 dollars on two items that were bad products or useless....but now I have this subox nano. Is this a good setup? It seems similar to my last setup, which was kangertech subvod...only this has more power , variable wattage and voltage, supposedly, sometimes I can't tell a lot of difference... Am I not having it turned up enough? Or do I need a different coil? Been using 0.5 coils..I greatly appreciate any answers to my questions.. I am still new to vaping and all knowledge that any of you give me is greatly appreciated, as I need to learn more about these things and products and so on...thanks so much...have a wonderful day.
