1. Search "Cignot Vicky ego-t cleaning" on YouTube for some great videos on adjusting and cleaning. I find that most either leak or give dry hits (dirty, burnt flavor) until you adjust them. It can be a bit of a pain, but it's worth it. The leaking has to do with the wick; how far into the tank or how far away from the coil. Learn to adjust, and you'll be happy. Unfortunately, most of these devices take a little tweaking to work properly... that's the nature of the cottage industry! If you find anything that works well, all the time, without any adjusting, PLEASE LET ME KNOW!
2. Get the Type Bs. Electrically, they're the same (same size coil, same resistance (ohms)), but for some reason I and many others simply feel like it's a better experience.
3. Get extra tanks. They're cheap ($5-7 for a five pack). It's so much easier to load tanks once every few days than every time one runs dry.
4. If the tanks you got came with hard plastic end caps, the part that gets poked, get the silicon/rubber ones. They're $1-2 for a five pack. Get enough to put them on all your tanks. It hugs the spike better and leaks less.
Once you get all that down, there are a few things you might want, though definitely not necessary. I like to use the USB Ego battery. Gives the option to use it as a passthrough, and it will charge with any standard mini-USB cable. Cignot has big ones (1000mah) for something like $22. Or I use a big mod with a 510-eGo adapter, available lots of places for $3-5. Well worth the money if you want a mod. I use many batteries, but only eGo-T Type B attys.
Welcome aboard! Hope that helps!
