Title: it work sometime
Review: i had this for under two year. use it alot. i got this instead of getting the nikon mb80 because of the price and the extra battery. well i love it. about six month later. i realized that the camera doesn't reconized the battery or unit. maybe both i don't realy know. i had two battery and one nikon battery. sometime it worked realy well other time it doesn't even recognize the nikon battery. everything works quite well without the grip. one other thing is that when i put the opteka on a tripod if i turn the quick release to tight the battery pop out inside the holder. if i don't turn it tight then it be won't be very steady on the tripod. anyway, most of my shotting are done without a tripod. it's working ok right now. very figitty. i'm now willing to spend more for mb80. however, i'm going to keep the battery. the reseason i'm giving it two star is that does work sometime.
