This is my only complaint with the duals. The flavor rocks in them, the hit is good the vapor is awesome...but I'm a heavy vaper and I hate changing batts all day long....and they force me to do that. I had one that drained 880mAh battery in 3 hours.
An 880mAh in 3 hours! Wow, you do vape too much. lol. I have a 1100mAh SLB kGo that lasts all day with these. My son uses a RIVA and gets 6+ hours (750mAh). We both have been using the 1.25 ohm duals from hoosier.
I have been using my Gorilla Juice dual for one month, and it is starting to lose TH. Vapor and taste are still there. I am going to put my Gorilla into a new dual and see if it hits better. Will let y'all know.
edit: OK, after 54 drops, and blowing one precious drop into a paper towel, I hooked up a new dual coil carto of Gorilla Juice. Put the old one on a fresh 1100mAh battery running 3.7+ volts. Good flavor, very little TH, nice vapor. Change to the new dual running same batch of 24 mg Gorilla Juice, same battery. The flavor is less blended. I can pick out the different flavors, feels more intense, large improvement. The TH is much better. Vapor about the same.
Conclusion, even if I can get one month out of these duals, I will change them out every one or two weeks (depending on usage). Now off to change out my Applewood...
