I bought my wife a brand-new v170 for her birthday. She wanted an extra charger to take to work so I bought this one. Big mistake! It simply would not fit in the charger jack. So basically, it's a worthless piece of plastic. Last night when my wife was cleaning the counter, she threw it in the trash, brand-new box and all. At $7.99 it wasn't even worth the trouble to try to return it. Don't make the same mistake I did!
