Build safety is provisional. Our 2026-09-29 search of CPSC recall data found no recall for this product, and no safety, heat or failure reports turned up in our sources, but we have not yet verified its UL/ETL or equivalent safety certification. The 9.0 is a placeholder until that evidence is reviewed, not a certified rating.
