Nike+ SportBand (Silver)
I got this for Valentine's Day and used it 3 times. The chip fell out somewhere while I was running and they refuse to replace it and said it wasn't part of the warranty. Don't make something that's meant to be removed and registered in your computer if you can't make a product that properly secures the most important part of the sportsband. I feel so bad that my boyfriend spent money on this horrible product especially when they refused to replace it.
