Got mine in yesterday. I ordered a couple attys with my batts and the "black" carts. Reports seem to be a tad better on the black carts.
In the beginning meh. Flavour was subdued, VP was great and TH was non existent. Vaping my RY4 100% VG. Would not do 3 successive hits, only 2.5. After about 1.5 hrs the atty seasoned and I am impressed. Flavour is there, VP improved and TH a 3-3.5. I am not for reckless so it is fine. Able to carry out the stress test of 5 successive pulls <---- that is a qualifier for me. There is a trick to these... now remains how long do they last
As I can no longer do reviews because of my status change, check out the eGo user group for an update later today.
