Battery's Fine; Service better
March 21, 2018
The battery's a battery and works fine in my several batteries. But two of the batteries were back ordered (which I knew when I ordered them) and the customer service folks were great, keeping me informed and also agreeing that, even 'though there would be two packages shipped, there's still be no shipping charges.

Great fit in my Klarus RS30, powerful battery!
December 8, 2016
I was using Panasonic 18650s's in my dual head Klarus RS30 (great flashlight, by the way) and they rattled around in the battery compartment. These Efest batteries solved the problem, they also fit well in all my other flashlights too. they're powerful too, a noticeable difference compared to the Panasonic 3.6V batteries. Don't know how they'll stack up endurance-wise compared to my other 3400 mAh batteries since I just got them. I own quite a few other Efest batteries (different sizes) and have been happy with the quality and performance.
ProsPower, quality, fit.
Consnone so far.

Great battery! It's higher load ohm does much better for my e-mod. But my Panasonic 18650 still last's the longest. But I want the power.
ProsStrong !
