Quality battery. With regard to consistency, the only gripe I see is the fact that retailers have not published separate listings for the two different known cell revisions (A/B). Without major importance, as both As & Bs are close enough to be teamed safely, imho. 
Among great power delivery, best deal on capacity/price ratio, too.
On the other hand, certain “rewrappers” seem to have no qualms in refilling their cell rewrapping/packaging machines with whatever they have at hand for whatever reasons. Example: Test/review of Gpower 18650 -25A- 2600mAh (Yellow-black) :facepalm:
