My son bought Angel eyes for his Honda Civic off e-bay. They didn't fit properly and when he did get them in, one of them burned out soon after.
Had it been me, I would have returned them, most dealers are pretty good about that, but he couldn't be bothered, so we have $120 worth of scrap sitting in the garage.
E-Bay is not the culprit here, we buy all sorts of stuff through them without problems, you just have to pick your supplier and check warranties etc just like any other company.
