i bought this ronin-m a year ago but haven't used it firstime I opened the box was to take pictures.ive included a 3400mAh battery which was fully charged and is holding its charge after 6 months. I gave it a test with a camcorder seems to operate well overall condition is good. __PLEASE__be aware that the battery is slightly swollen can be removed if you wish also it can come in a DJ1 hard case please contact me before I post thanks
