I had an ipv 4 and that imploded in my purse at best buy a few months ago, so I made a post here to see if it was the batteries or the mod,turns out you guys were right it was the mod,after some thought I replaced it with a sigelei 150 TC which normally does pretty well for me,but I've noticed it heats up slower than my ipv 4 did,also it seems to have trouble heating lower gauge wire coils,no matter what wattage I try, I seem to get this little tiny harsh hit,with max vg,with any coil made with lower than 26 gauge wire. I haven't seen anyone else mention this,asmodous didn't reply to my email and I haven't been able to get any answers on YouTube so I thought maybe someone here could answer this for me,is this some kind of safety feature or is it possible I just have bad luck and got another dud? Thanks
