2 weeks in with these attys and I will say that they perform outstanding between voltage load 4.19-3.7, once my AW P18650 2600mAh 3.7v bats voltage load drops below 3.7v, the performance dramatically decreases IMHO and the 1.5Ω/2.0Ω AMG Universal Hybrid's are still going strong and have consumed lots of juice.
The flavor production is simply amazing, the vapor production is as well simply amazing and the th is simply perfect for me on both now. I do still flood them here and there but no biggie for me, on this rate these attys should last at least a month with serious usage. They do get quite warm to the touch when chain vaping but all attys do but these have the tendencies to cool down quickly.
If I blow out the gunk if flooded, clean the threads and contact when flooded and or at the end of the day...then soak'em, the next morning they work just like they did the previous day. Most of the drip tips I have all fit nice and snugly onto the sleeve with very little pressure but whatever you do, do not cover the opening on top of the drip tip while seating it into the sleeve...you will flood your atty no matter how many drops you have in it.
Overall, I give these bad boys a +15 from my experience.
+5 for Vapor Production
+5 for Flavor Production
+5 for TH
I am using Minnesota Menthol at 25mg nic lvl and 70/30 pg/vg...
*ATTN: Do not over torque any atty..
