Anyone?? Anyone?? I have a 18650 Manhattan and I love it. Some complain about the negative battery contact not having an insulator and my only advice is don't put it in your pocket. Other than that I don't see this button EVER sticking cause the magnets are powerful. I bought some Vappower IMR 26650 high drain 40A / 60A 4200mAh batteries. I couldn't find any reviews for the batteries because they are fairly new, but I took a plunge on them. If they suck, I'll just recycle them and try to get some Sony 26650 or the Efest. Let me know if you own a 26650 Manhattan or the new 26650 Vappower batteries and what you think of them.
