PROBLEM: 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.

SOLUTION: Good Review

PROBLEM: Did anyone else notice an smell that lingered for weeks? It's nauseating! I don't know how it could have possibly gotten there, if so many others haven't noticed.

SOLUTION: Bad review

PROBLEM: Interesting book. Enjoyed it.

SOLUTION:
Good Review
