I would feel sad about it but I’ve had horrific luck with my RovyVon flashlights. I’ve had 3 of them and 2 have lasted only a couple months before they stopped charging. I did get one swapped out under warranty but the replacement similarly failed. I could swap them out again but in the end due to their unreliability I’ve just stopped using them altogether.
To be fair, I don’t know if the clones are any better. I just picked up a jetbeam as a replacement and I’ll see how it lasts. Hopefully it’s not just an issue inherent to these tiny batteries.
