Just as an update, my Saber Touch finally died today. Well, the batteries dies and not the touch itself. LOL. Anyway, I got about 5 1/2 hours from chain vaping on a normal 510 atty using two Ultrafire ICR 123A 880mAh 3.7V batts. So, pretty impressed that they lasted that long considering how much I sucked on them today. But I will tell you, when they quit, they quit! I thought at first I had blown an atty. Changed atty and still nothing. So figure it is the batts. If I let it sit for a bit I will get a short sizzle sound then nothing, which a typical batt will self charge a little if left sitting. Looks like when I get paid Monday, I will have to order 2 or 4 more of these batts to keep on hand.
@Sir - I am glad you didn't take anything personally, but wanted to give my honest opinion on this device. I have looked at MANY others, including yours several times, and I am VERY happy I chose the ST. Now, if I could only afford that Glow in the Dark blue one.....
