Pros: - They seem to pack a real punch, at least according to my multimeter
- Since the only place in my vicinity sells these for about 20$ for one, this makes it a bargain.
- I've being using them for about 20 cycles and the performance is still as if they were new.
- They are nice and smooth and fit in my flashlights just fine.
 
Cons: - Being batteries, they are pretty expensive. Although they are a lot cheaper than I've seen.
- The design is ugly if you care about these things.
 
Other Thoughts:  
Bottomline: Good quality at a good price. I've used them for a while and the performance hasn't deteriorated a bit. The capacity seems as promised too. If you are buying a flashlight here, order these along, you won't regret it.

Pros: - Protection seems to work (won't light up SKU 10855 )

- TrustFire has invested in wrap design (hopefully flame figures won't forecast bad incoming)

- Two charge cycles are behind and I'm happy with batteries performance.

Cons: - There is a weak insulation spot located at the side of the minus pole, just where the protection circuit conductor is bent. The conductor will easily come visible, because it barely exceeds the battery maximum diameter. For example, if the battery side rubs with flashlight battery tube, then it is good to wrap one layer of insulation tape around minus side (but don't cover the minus contact).

Otherwise original insulation may wear out right in first use and bare conductor may cause dangerous short circuit (if the flashlight tube is conductive material).

Other Thoughts: I don't have accurate measuring devices, so I won't comment promised capacity.

With these batteries, it seems that you can reach to the promised working times, what flashlight manufacturer have published.

Bottomline: I recommend these batteries, but advice to wrap insulation tape layer to the minus side. If there is a risk that original insulation rubs somewhere.

Perfekt

Pros: These 18650 Batteries are protected.
Really good capacity.
Nice new design, gives it a classy look.
 
Cons: - These batteries are a little on the long side, about 68mm.
- These batteries are a tight fit in my charger (Ultrafire WF-139)
- A little expensive compared with other Trustfire 18650 batteries.
 
Other Thoughts:  
Bottomline: If you looking for a pair of good 18650 batteries, don't look further, you found them here.
Good capacity (don't know the exact measurements because I don't have a charger which can measure this)
