Query: Not working after 1 week

I loved the item for one week. Then it ceased to work. I threw out the box and hope that I can return it for a new one. If it works, its great. Hope I just got a bum one! I just wish that the wheel guage didn't move as easily as it does because after folding up my jogger sometimes it moves and I have to adjust it so it doesn't hit my wheel.
