Seems to hold the juice.
I'd read in a review that these were a little on the large side and wouldn't fit in a flashlight without peeling off the stickers. A test fit in my Nitecore TM06S proved that to be true. After removing both stickers and cleaning off the excess glue with Goo Gone, they slipped right in. I might have gotten by with just taking off one set of stickers as they are now actually loose. As far as providing power, they seem to be up to the task; they lasted the advertised time on my TM06S.
ConsMight not fit in your device without removing stickers.

So-so
Great battery. Have to peel the labels off to get them to fit my headlamp; a bit ridiculous.
ProsBig battery
ConsCrappy labeling that interferes with their fit.

Stickers made it not useable
This battery wouldn't fit in my device. I didn't dare put it into the device because it would stick. I had to remove the stickers down to the plain black inner battery to get it to work. I spent an hour trying to remove the gooey residue from the stickers so it wouldn't ruin my device.

Love these batteries.
Way better than primary batteries. Most powerful mAh rating that Efest makes in a 18650 battery. A bit tight of a fit in my Terralux TT-5 flashlight. Removed a small sticker on the battery and it was great. Good runtime on my torch.
Pros3400 mAh rating. Super bright with these power packs.
ConsLittle tight but workable.
