Please note that this review is based on Customer Service. Not the product, because this is a great product. I have MS and I've been coming to terms about having to use a wheelchair. Not me. That's not gonna happen. So When I saw a commercial for the Zinger I thought ok its not a wheelchair. I can do this. I ended up buying it on ebay. I saved $700. It was brand new. Fell in love with it. Had it for 2 months. One day I decided to go to grocery store. As I crossed the street up the corner ramp my Zinger almost threw me to the ground. Apparently the caster broke. Had a friend come pick me up. Called on a Friday to get a replacement. I was told no one was there to answer my question about part replacement. It was late. So I was asked for my contact info. Told they would get back to me Monday. Didn't happen. So I called back. Was told to take photos of chair. They gave me a forwarding email address. Waited for a day. No return response. I called back. Was told that I was given the wrong email address. So they gave me another. That email didn't exist. I finally gave up on the company and found part on ebay. Thank God. So great product awful customer service. What I would still like to know was this broken caster just a stroke of bad luck, or should I tread gently? I should also mention the name of the company was First Street
