Manafont has been the place to purchase them from in the past. My original set of 3 were real and performed fantastic in my Trustfire TR-J12. The Trustfire 26650’s were never actually 5000mAh, but always tested from forum reports at 40000-43000mAh consistant. They are also protected cells, but I will look into the King Kong’s for my next purchase since they are getting good reviews. Thanks.
For Reference, below are the tests for the Trustfire 26650 cells as reported from members, Benckie and HKJ
