The only problem is that the handle is totally unreliable and not working properly! One can maybe turn on the DSLR and 2-3 make 7/8 photos in portrait orientation before the camera screen indicating that the (previously fully charged) battery will be empty. Ergo: handle degraded battery out, starting in the Cam and lo and behold, the battery is full !!!
So either the contact between BG and the camera does not work, or in the BG contact the battery is not working. Either way, the part is defective and must return. Unfortunately, this seems to be an isolated case, so I do not'll test it again ...!
Sorry, no buy recommendation for Meike (made in China)
