Simple to use and quick to charge with. Love the informative display! Shipped relatively quickly, given today's "delays".

5 of 5 Good Charger. January 15, 2024
Reviewer: James Kinsey from Boulder City, NV United States  
Really not much to say at this point. The battery is for my Nitecore SRT7i 3,000 lumen flashlight which works very well! Haven't had either product long enough to make any kind of judgement as to longevity. The battery charged just fine so I threw a couple of 18650's at it that I knew were deficient. The charger called them "poor" so, it appears to be working.
