This is just a black handle here and it has a plug into your iphone or android no need for battery. It has a button to click on to take pictures and it extends to 88 cm with different angles.
I turned it on extended it and use one of my brother's Iphone just to record not take any pictures but it turned out good. Good picture shot good recording clear picture.
I took a picture from my digital camera and showing you how it works and i didnt press down on the button or anything and I must have and on my brother's phone the next day it had taken about 215 pictures of myself. It is that good.
