A friend and former co- worker has join the vaping experience due to my pushing and advising. I let her use one of my Riva's for a weekend and she was ready to quit and start vaping. She ordered her own Riva's and I DIY e-liquid, so I gave her a bunch of samples. then one night she calls me at like 10:30pm , (im set in my ways, usually in bed by 11) and she is frantic all her batteries have stopped working and they wont charge and they look like they are charging and well that was a 2 hour convo on the phone, she comes to the house at my invitation granted, to borrow a battery or two till she can order more and get them in the mail. Ok, here's the problem, she knew her chargers were prolly the problem frying out the batteries. At this point she had killed 6 yes I say 6 Riva batteries. She returned my 2 Riva's and 1 510 fried too. Now, I did lend them to her, knowing i was taking a chance by doing so, but i was really upset when she returns everything and doesn't say a word about them not working any more. So I wound up having to buy new batteries. when I told her they weren't working she kind of rushed off the phone and it's been hard to get a hold of her lately, hmmmmmm wonder why??!! So , guys what would you do???!!!
