After vaping for over 2 years I've learned one thing, listen to all the suggestions but take it with a grain of salt. You have to find what will work best for you and go with that once you found it. Like juice all things are up to the users liking. I use the 1300mah spinner and vivi nova and have not had one issue in about a year. This set up works for me but others may not like it at all so the best thing to do is try it for yourself and see what your go to device is. Most of the delivery devices are priced low enough so you can try different thing and go from there
