Good capacity
I tested 4 batteries at 7.4 volts drawing a continuous ~.5 A. With a cutoff voltage of 6 V the batteries delivered 6.2 AH. I am satisfied with the capacity despite it not reaching the 6.8 AH expected.

Perfect for Flashlight
I wanted an extra set for a new flashlight so I'd always have charged batteries. These are perfect- thanks for the fast delivery too!

Very Robust, But ...
I purchased this battery for a diving flashlight. The flashlight uses a single Cree LED, & performance is akin to holding the sun in your hand. I realize I'm playing with fire using an unprotected cell, but this one has such a high current rating, and fits perfectly. I will not be leaving it in the car on hot days. From what I've gleaned from forums, the protected Panasonic version of this cell is larger in length & diameter, cost considerably more, and might not fit my flashlight. I am happy with this battery, but will use & charge it with caution only when the protected battery that came with the flashlight dies in an emergency situation. A bomb waiting for the perfect conditions to explode ? - Lets hope not ...

Long lasting battery at a bargain price
Orderred these because of price and found that they last longer than other 18650s costing more. Down on power as compared to 3.7V batteries. Can't beat the price though!
ProsPrice, price, price and price... Lasts longer than pricier batteries.
ConsNone if price factors in.

Great Battery for the Futaba 14mz / 12z
Made up two packs and cycled both at 2900mah using a Hughes RC charger/cycler. They will fit into the stock Futaba case perfectly if your very careful. I soldered on the original tabs by first grinding out the spot welds on the old cells. Then I tinned the plus side on the new cells using a lo heat soldering iron. The minus side I had to grind the plating of the new cells and use a soldering gun to tin. After soldering on all the tabs I carefully ground down any high spots and reinstalled the case top.

Panasonic 18650
I own a couple pair of these; LONG life. These are excellent all the way around for vaping. Last 8 hours at 3.8-4.0V with heavy usage. Should be good for a ton of hours in a flash light as well. I've been through ~40 18650's of "other" brands and so far, these are the best I've tried in terms of sheer capacity, better than AW and others, in my opinion. Probably somewhat expected with the 3.6V rating, but I don't notice the difference between 3.6 and 3.7V. Personally, I'd rather have the capacity, and these batteries deliver in spades. Why waste money on all the re-branded stuff and not just buy the real thing? They've passed my initial tests over 30 days, but I still need to see how they fare over the long-haul. If they make it to 3 years or longer with once daily recharge cycles - I will never buy another type of 18650.
Pros--Capacity --Capacity --Did I say CAPACITY --Vape for 9 hours @ 4.0V --Tons of current in the upper half of the discharge
Cons--3.6V - down a bit on punch and may not work well in constant high demand conditions --Current seems to drop off a bit after mid-discharge, requires a voltage adjustment up to compensate (with VV devices) --No button top; may not work in all devices without a spacer. --Price (but you do get what you pay for)

Excellent battery
I've used it with my Fenix PD35 and it's a great experience. I bought from Battery Junction a Nitecore D2 Digicharger, plus the PD35 and everything is fine. If it fits your device, and it's a non high drain device, then it's your best option.

Great battery unbelievable storage
I use this in my e-cig it lasts longer then any other I've used I can go almost a 9 hour shift on this battery .
Proslast a long time. probably the biggest battery available in 1860 size
Constakes almost 2days to recharge. doesn't work right with everything because it's flat top on the positive pole.
