I am using these in my e-cigs instead of 16340's where they will fit, and the difference is amazing. Thank you.

Unreliable quality & very inconsistent
July 28, 2014
I've order three sets of three of these batteries for a electronic cigarette mod. My review is a mixed bag. The biggest complaint I have with these is they are completely unreliable or consistent. The first set of three I bought were great; put out a lot of power, had a very long charge and lasted for about a month before they began to fade. The second set of three I bought were bad from day one. They would barely hold a charge for more than a few hours and were pretty useless after about a week. Finally the last set I bought was similar to the second purchase; They performed well for about a week, but shortly thereafter they had very poor power output and terrible life from day one. I have trouble with 18350's as there really isn't any super reliable brand; I would love to see Sony or Panasonic put out a 18350, but for now we have to settle with no-name brands. I learned my lesson after the third purchase and it's on to a new brand.
When they work, they have fantastic power output and a great lifespan/charge.
Extremely inconsistent, more often than not you'll get under-performing batteries that will hold a very poor charge.
