I placed an order for wheel chair locks for an 8" caster Drive chair. The set of wheels they sent did not fit on the chair and when I called customer service the girl I spoke with was very rude when I called to see why they wanted to charge me not only for return shipping but a re-stock fee for their screw up. The girl in their customer service was one of the nastiest customer service people I have ever had the misfortune of speaking to. Stay away from this company, far, far away or at least lower your expectations for customer service. I am sure the wheel locks would have been fine if they were the correct ones.
