Vitamix has settled a class-action lawsuit, which means you might be entitled to a $70 gift card. The suit is over a blade; where "certain blenders were defective and depositing tiny black, harmless flecks into food and drinks." [Source]
Some Vitamix owners have already been notified but you have until September to submit a claim at blendersettlement.com
Consumer Reports, says as many as 6 million Vitamix blenders are affected.
In order to qualify, blendersettlement.com, a site dedicated to the settlement, notes that the blade assembly date must be on or after January 1, 2007 until October 1, 2016 for household blenders. The date is reportedly located at the bottom of the blender container. Eligible members can then either mail in a claim form or submit one online. [Source]
