Hi, My wife and I just started vaping about a month ago. We got set up with cool fires with kanger tanks which my wife's took a dump after just 2 weeks. We went back to the place which sold it to us (which is over 100 miles from us, we camp near the place on the weekends during the summer ) and wanted to upgrade but the place talked my wife into a cheap k-box 40 watt (which it burns the juice with the kanger tank at 25 watts) which the k-box I seen as cheap as 17.99 online compare to the 65 we spent on the cool fire we didn't know at the time so we got ripped which I will mail the k-box back to them and tell them to jam it. But anyway I got her a Sieglei 75 watt single battery for 85. It blows thru the battery's like crazy and juice with a artic tank vaping at 64 watts. Now my cool fire is taking a dump lol go figure. with some looking online (not knowing what i'm doing) but a whole lot of reading I ordered a Sigelei 150 tc for me with a freemax sub ohm tank (and of course only see the good reviews until you order then I see the tank is not that good) But anyway my wife is already getting sick of the sigelei because it's really heavy and the fast drain on the battery's. Ok I think you see the picture, 47 million dollars later we are back at square one. Please help me. Some of the questions I have is for me first....... What will be the best battery's for the Sigelei 150 tc? I ordered the Samsung INR 18650 25R Battery - Flat Top. Then of course the Starre Sub Ohm Tank by FreeMax. Do you have better choices than what I ordered? On the tank I chose that one because of the flavor it says the tank gives and the wattage it can go to I guess. Now my wife...... I was thinking the sigelei 150 tc or the plain sigelei 150 watt. The tank? I have no clue because i'm so confused right now. She vapes at 64 watts now and has no interest in dripping or changing to the temp control where I am at a later date but wants a good tank that gives good flavor and can take a coil at least .02. She is saying she likes the artic but it seems like the artic by horizon's tank is small? I have no clue, and the reason for at least a 100 or a 150 watt for my wife is if I got her another 75 watt and she vapes at 64 I think she is kinda close to maxing the mod out where a 100 or 150 it's not pushing the mod that much. I'm I thinking right? Please help me I just want to get all this stuff straight with good tanks the proper GOOD battery's and of course good mod's. Tired of wasting money and just want to get this done. I'm back to smoking and want to stop and I kinda get the feeling my wife is right around the corner to start smoking again due to frustration. And yes we only use quality juice. Thanks for your help. And i'm really sorry if I sound all confused because I am. Ok i gotta go now and beat my head off the wall again.
