    Since this latest batch appears no better than the cheaper gray Trustfire 2400, you might as well save the $2 and get them instead: sku.5776. Or spend the xtra $$$ and get the Soshine 2800's.

    The symptoms are ~20% less capacity and a reduced voltage during discharge. You can do a side-by-side comparison with an old batch and see if your lights die off ~20% sooner. Having a charger which logs this is VERY helpful.
    What's up with the scrubbed LED driver IC markings?
    What are they trying to hide?

    Having it log the voltage under load is definitely very helpful. It's quite labour intensive without something to do that for you.

    I also bought these, hope I can get a refund. Why has no one posted a critical review yet?

    If you're looking for an alternative, try the blue-white solarforce 18650 with 2400 mAh. They have a tiny little bit less capacity than the original TF 18650 but they can handle much higher current. Don't know if DX sells them.

    Still the same bad batch or they have already fixed the issue?

    I just got mine Shipped 1/17/2012

    It's the same gray logo, not holographic like the ones on your right picture.

    Fake? Damn!

    Because they are different yet again from the poor quality cells I got (cells E & F in my graph) I think they need to be tested before we can say what they are.

    i agree with all of the above.
    i'm ok for cells at the moment, but the future supplies of these (once) excellent cells gives me the creeps.
