I am thinking that this will be my second regulated mod. I really think there should be more hype around this product considering that it only has positive reviews so far. From what I have seen this box has build quality rivaling the sx mini. The only potential downside that I can foresee is that the firmware is not user upgradable which is not a huge deal considering that the only things that would be fixed by a firmware update is the automatic wattage change when switching to temperature mode and improved battery efficiency. What I want to ask you guys is whether you foresee something better than this product coming out in the near future. The only other products in this category seem to be the ipv4, ipv3li, and the new sig boxes; all of which have lower build quality from what I can tell. If those are the only other options for a dual battery temp controlled mod in the near future I will probably pull the trigger on the snowwolf.
