Are nonstick slow cooker inserts safe?

Reviewers are split. Some brands now market PFAS/PTFE-free ceramic nonstick coatings as a healthier alternative to traditional stoneware, and verified-purchase reviewers praise the easier cleanup. However, community threads flag durability concerns — nonstick coatings can chip or wear over time, and a few owners report coatings peeling after heavy use. Traditional glazed stoneware remains the most durable option.
