These seem like good cells. I love the white and blue wraps. All 4 cells weighed 74.5g each and each had a shipping voltage of 3.48v. Running a discharge test at .2C (1000mA) all cells came in at around 5000mAh of capacity: 4993, 4994, 5003, and 5038mAh. I forgot to take a photo of the one discharge test, so I took a photo of the finished recharge cycle on my Nitecore UMS2 (5029mAh). They are slightly larger in diameter then some other 21700's, but they still fit my Convoy S12 which has the narrowest battery tube of all my 21700 lights, but there is no room to spare. It took 5 and half weeks to be delivered and they were well packaged and they all had individual plastic cases. Will have to see how they hold up over time, but I doubt that there will be any problems.
