Pros: The true capacity of this cell is about 2250-2350 mA. Thats a very good score, because many other cells that are declared as "2400" or "2600" have less than 2000mA.
The cells feel solid in your hand, the buld quality is very well.
Protection circuit works.

Cons: The price and quality is ok, so there are no cons.

Other Thoughts: This cell is

Bottomline: The thikness is about 18,5 mm (at the larges place, the plus pole) . The protection circuit adds about 0,4mm.
Length: 68mm
The cell is a very little bit smaller than sku 28677.
Sometimes people get problems to fit their 18650 cells into her flashlight host. With this cells i never experienced problems like that with a lot of different hosts.

Pros: Powerful and reliable. Hold a charge well and runs my p7 flashlight perfectly. Nice design, and the price is outstanding

Cons: Only con I can think of is they come taped together, so when you first use them, they are sticky from the tape. I rubbed the sticky tape residue off with my finger, that seemed to work well.

Other Thoughts: I have never used this size battery before, and I am impressed. I popped them in my MTE p7 and bam....SUPER bright. They are really powerful, and seem to be reliable. I charged them with my trusfire all-in-one charger, they took a charge well, and are working perfectly

Bottomline: Nice battery for the small price. They are also "protected" so that is a plus. If you need 18650's, and don't want to spend a lot, you can't go wrong with these!

Pros: capacity quite fine, protection included, makes it longer appr. 1,5mm.Overcurrent-protection is very rigid protection-chip can be removed, battery still has a second layer of isolation. battery terminals may be soldered easily...battery comes charged to about half capacity - best condition for storage!

Cons: Overcurrent-protection reacts within 30ms, current climbing over 2A - means: driving a motor, e.g. a drilling machine, makes it neccesary to "delay" overcurrent protection - can be done by modifying the protection chip - but don“t blame me

Other Thoughts: be careful working with LiIon! They are safe, when driven within their limits - and dangerous, when outside!

Bottomline: ideal for replacement of (most same size) commonly used LiIon in power-tools.
