Ninja support replies to customer concerns regarding the Prop 56 Cancer Warning on their blenders:

We definitely understand your concerns. We would like you to know that we are required by law in the state of California to include the California Prop 65 Warning. We include the warning in abundance of caution and to comply with this California warning mandate. The mere presence of even one of over 900 chemicals requires this warning and since it is not feasible to test for every single chemical, we're including the label with our products. Please rest assured that all SharkNinja products are in compliance with all applicable laws and regulations. We hope this information helps. The Customer Support Team

According to Ninja, they apply the label to avoid testing for 900 chemicals that may cause cancer, which renders the warning rather meaningless. They should know the materials in their product and be able to specify what warrants the warning. This would allow customers to make informed decisions about whether to purchase Ninja products. This lack of transparency seems quite shady!
