That's not how jury selection actually works in this country. Personal experience in a relevant field is generally not a justification for removing a juror for cause. A product preference is not a justification for removing a juror for cause. You can of course use one of your peremptory challenges (i.e, no justification required) on such jurors, but you only get a handful of those (1-6, depending on the jurisdiction).
