Pros: extremely accurate!!!, lets you know where the wires are.
Cons: It takes a 9v batterie. I always have plenty of AA or AAA laying around but never any 9v. I actually had to go to the store specifically to buy one. Kind of silly, but still a con.
Pros: Everything it promised to be. Love the color. My son and I both have a PS3, so the colored controller makes it easy to distinguish whose controller is whose.
Cons: Didn't come with a charging cord. For the price you would think that Sony would include a way to charge their re-chargeable controllers
Overall Review: You can still use the charging cord that came with your original controller (the one that came with your PS3), but that means that you can only charge one controller at a time
Pros: All around great product. It was as described. works on Samsung Galaxy S3.
Cons: None
