I have contacted Bloog twice....once through their website and once by emailing a@bloogplanet.com but I have gotten no response. I have at least $200 worth of their products and feel like I am a good customer. I even paid for 50 blank cartos a few months ago and then waited over a month to receive the carwtos while they had my money the whole time. I would like a response to my dead battery question! About two month old 78mm batery that has stopped working and charging.
