For the most part I love this mod but I have been having one problem with it which I was wondering if any of you have had.When the batteries are dead and I switch to a new set the first hit is a massive surge which has popped 4 different attys of mine(over $50).I have tried firing it without the atty attached first but when I put the atty back on still the first hit is massive.The only way my attys survive now is I over drip them with like 6 or 7 drops so the first hit does not destroy them.I was real ...... when my HH357 popped that I have used for just over a year.Anyone else have this issue with the Zmax?
