I have been testing the blaze a bit more now and I can say that on the same settings and with the same tank as on the San DNA80C, the blaze performs better. I can't give any numbers but it feels like a battery on the Blaze last for at least 2-3 times what it would do on the San DNA80C. Out traveling now but when I'm back I can see if I can get some more data. Right now I can't use the San because frankly it would drain my batteries completely before I had the chance to recharge them and the Blaze is much better.
However, the Blaze can't beat my Stubby, San V1 non DNA, Raga AIO, Zaion etc. It would be awesome devices if we could get a better performance curve or a fix to sort out battery usage.
