Negative Positive
Title: More trouble than it's worth -- even at under $10 . . .
Review: This was a pain to install -- and it only "works" with the battery pack attached. This is relatively useless in Portrait view as you have to take your hand out, and move it out of the way before you can use the shutter release on the battery pack in Portrait view. Limited usability, it's a pain to install factors make this a waste of any amount of money.
