This product works great with my Sony NEX 5.I was a bit disappointed when the first adapter that was sent to me didn't fit at all. You are supposed to insert batteries through little holes, and as soon as it snaps in place, you're suppose to twist or pull back so the battery will make contact. The holes looked too small for me, but if you force them in with enough force, they snap into place. But now that I've got this one right, it's pretty sturdy.

Ex Output:
Good Review

My cat loved this toy at first, but then got bored of it. So now, he loves nothing more than to chase the ball into it whenever he's ready for a nap. He especially likes knocking down and jumping all day long in order to get enough sleep until I can give him his toy again. After seeing where my dog had chewed through another brand's plastic mouse toy, both cats have been trying to find one like this. This is great quality.
