Hi all. just wondering who out there has the ipv4s 120 watts and what do YOU think of this unit? I just purchased one for myself and wanted some opinions on it. Supposedly it had fixed some issues with the 1_ipv4 they have removed the charge port I see and I think the chip is different but I'm not sure.. it can run nickle, titanium, and kanthal. also it has itemperature control. I've been a fan of the ipv series in the past and used mine until they wore out. I had the ipv, ipv2, ipv3, and now I've purchased the ipv4S. I never had ANY issues. with the others. this temp control is all new to me as well as using nickle and titanium wire. I was just wondering what your opinions were on this unit?? Thankso so much!!
