I do recall all the stuff you are saying. I worked as a casino floor supervisor and we smoked cigarettes while on duty on the floor in customer view. Ashtrays all over the place. Times have sure changed. I decided to vape because I wanted to stop smoking and thought it would be the perfect substitute and solution for me --- and it is!
My coils last on average about 2 weeks. I also keep the air flow control on fully open - I do not like a tight draw and it works very well for me - 100% satisfied. I was on 6mg (.06%) nic juices for a while and I started buying one bottle of e liquid at 6mg and one bottle at 0mg and I would mix them together to slowly decrease. I am really good at math but there are calculators at there. I would decrease it by mixing 3/4 of 6mg (.06%) and 1/4 of 0mg to bring the nic content down to 4.5mg , for example, and so on. I stepped down slowly, started at like 45mg on different equipment. I now buy 3mg and 0mg, do the mix thing and and am around 1.5 to 2 mg. It is not mandatory for me to get to 0 but I keep going down and think I will eventually get to 0.
I buy only authentic Kanger coils. Another thing that I do is I have an old medicine/pills container - a big one and I rinse my coils in very hot tap water and then let it sit in a Styrofoam cup for a hour or two, rinse again, let it dry naturally on paper towels for a day or two and put in the old medicine container. I keep these extras in case I am running low on coils and can usually can get another use out of them. As you get more familiar you will just know if it needs to be chucked or rinsed.
Also, the toptank mini lets you build you own coils. I am vaping 6+ years and only started doing that - they helped me out on here and it really is easy -- don't know what took me so long and it is so MUCH less expensive. One you buy the rba piece (if it did not come with your kit --it is like 7.99) you just buy wire, cotton and a coil jig winder thingy and a ohm tester and for like 20 bucks or so you can probably make coils to last you for years! When you make your own -- you have access to the coil part and if it looks good you just have to swap out the cotton.
I am a big Kanger fan. I like easy! I have a toptank nano, the top tank mini and a top tank mini c. Only the top tank mini can take the rebuildable stuff but all three of these vapes use the same coils and the same batteries. Again - easy! And, I bought a battery, called the subvod mega by Kanger that is tube shaped and has the battery build it. The top tank mini fits it perfectly and it is a great spare battery to keep around just in case.
I know there are lots of people that love vaping with temperature control. I've not ventured into it because I am fully satisfied with the wattage I am at.
There are so many benefits to vaping. It has gotten to the point that I sometimes do not vape for hours. I never felt that way with regular analogs.
Keep it up! And congrats again.
