Welcome and glad you joined. Great choice.
Mod battery is built in so you just saved money (buying batteries,charger&meter). Watts are fixed so you are using around 1.2-.5 ohm coils (not sub ohms) so should get great flavor and not have trouble with equipment setting problems.
The tank is the only area you may need to read up on. Could check:
Tank Flooding Explained | Learning Center | VaVaVape
Tank type atomizers... For new vapists - how they work | E-Cigarette Forum
TFV8 leaking
Also could take a look at "how to tell when to change coils".
Ohhhh this is exactly what I'm starting to look into! Thank you for the links! So I placed my first order this morning from myfreedomsmokes

I'm so excited to receive my package! I got the innoken sd20 I meant to get silver but in all my excitement I completely forgot to change it to silver from black. It's ok bc I kept going back & forth between the two. I know a lot of people think this is an ugly mod or lame with the skulls but I think it's super cute & you can switch out the panels & it's basically the same as the t22 but it has that chip and I figured the chip has to add somethjng positive right? Still can't change wattage or anything but I think I'll be ok?? Hope so!
I got the starter kit which comes with the mod & a prism tank battery charging cable & like you said it has the battery built in oh & if I'm not mistaken a beauty ring comes with it as well I have no idea what that is.
Anyone??
Along with the kit I ordered a pack of 5 coils but at the last minute I realized it said innoken guardian coils & so I deleted those but I am now desperately trying to figure out exactly which coils I need or what things I need in order to make my own. I'm pretty crafty & am always always down for diy especially if it involves saving a buck or two.
The flavors I got are all mfs flavors from what I've read they might need to be steeped or maybe since they are mainly fruit flavors and small (30ml) sizes they might be ok out of the box. I already have one blueberry flavor that someone gave me that's steeped so if I have to steep these at least I have somethjng to use until they're ready

Flavors I ordered:
Watermelon
Strawberry
Vanilla ice cream &
Juicy fruit
Anybody with experience with mfs flavors and specifically these and has any tips to give me I'd appreciate it. I am going to mix the straw with vanilla ice cream and the straw and watermelon and the blueberry and vanilla ice cream. Oh I got a variety of nic strength & vg pg ratios I got a 3 two 6's & one 12 & mainly 50/50 one 70/30 propylene glycol /glycerine and one 70/30 glycerine / propylene glycol.
Im sure to find out my personal preference of ratios & percentages with this order & fell here on out I'll know what to order.
Whew ok that was the longest post & ive probably bored some of you to tears. My apologies I'll keep the rants to a minimum here on out I just had to share bc I can barely contain my excitement. This is going to be the longest 3-4 days until my package here. I hope I have it by next Wednesday I'm in California not sure where mfs is but I think they are in like Virginia or somewhere near there. Please please let my package get here safely and quickly dear Lord!!!!!!!
Thanks for all the responses and the warm welcome guys!!
