I have zero expierence in modding and still trying to learn how to solder correctly;but I am wanting to learn.I recieved from TI an offer for samples but what should I get?! Can someone please advise me on what to order so this generous offer is'nt wasted? I prefer 5 volt for vaping and I have a non-working PS passthru(old style),I want to fix and then several box mods both 3.7 and 5 volt that no longer work to start with. I want to try the Alto-mizer kit also.Any advise on what parts to get will be greatly appreciated.Thank you all.
