I've used two different micro USB cables plus the one they shipped and none can detect my device... Also the device has been charging for over 3 hours and green light will not turn off (still beeps red/autolocks upon firing and power adjustment button no longer works) seems like these are very faulty even tho the [functioning] product was amazing.. am looking to get a refund or FREE fast fix. (For how much this device costs...). otherwise I'm taking back the charge through my bank and reporting them
