Prop 65 warnings are mandated by California for anything that may have even a precursor to cancer, such as coffee or plastics or anything with the slightest precursor. We believe that our products are completely safe for consumer use. If any Prop 65 listed chemicals were to be present, we believe them to be within safe harbor levels as published by Prop 65. Our products may use Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Bisphenol A (BPA) and other enclosures.  Styrene is a precursor chemical used to make ABS plastic. Prop 65 identifies Styrene as a chemical that can cause cancer. Please note that PC and ABS plastics are not listed polymers under Prop 65, but the identified precursor chemicals are listed; therefore, out of an abundance of caution we decided to adopt this marking to alleviate any legal issues that could arise from an improperly marked product sold in California. These warnings are not required by FDA or other Federal agencies.
