you're just fishing for reason not to at this point. Just like everything in life, you can end up with something that isn't the "norm".. Ie a defective TV, car, etc from the most reputable companies. Medical procedures are never 100% as you can never predict the outcome 100%, as your body's response is a big contributing factor. All you can do is look at the big picture, and see whether the majority produces an outcome you are willing to risk paying for.
