I Got (1) VK Black Batt That Does The 3 Blinks and It Does Not Vape. I Used it only a few times, charged it up cuz it stopped vaping and starting to blink without stopping, put it in the charger (the old USB charger one that busted) and it seemed to charge, but just 3 blinks & no vape. The Battery is also loose in the casing (so is my other batt (The Nice looking Black Batt with the lines), so it actually rattles (no I did not drop it). Steve was nice enough to send me the updated charger. Its Over 2 weeks old so I'm out of luck.
I Like the VK's But The Atoms are Suppose to Be Disposable & Not The Batts I Hope. I Ordered Another VK Kit I Got It Today, it Works & I Like It Until It Gets Too Hot, I only use it when I go out for quick errands only anyways. I can't use it as my main vape.
You will know soon enough if its bad or not.
Keep Vapin!
