❌ Coating peeling and rubbing off is documented in multiple 2025 accounts — “first bottle I received — all the paint rubbed off onto the other items in my work bag” and “purchased the 1 litre reusable bottle — not much use and the coating is coming off.” Customer service response: “wear and tear” even on new bottles. 

❌ Mould inside non-disassemblable mouthpiece documented — a February 2025 buyer found “visible mould inside the mouthpiece — an area that cannot be properly cleaned because the lid doesn’t disassemble.” Customer service refused a replacement lid, calling it “not a manufacturing fault.” 

❌ Metallic or chemical taste documented despite ceramic lining — “bought the ceramic reusable bottle and from the first fills it makes the water taste metallic” per a buyer who missed the 14-day return window. Multiple similar accounts exist. 

❌ 14-day return window is restrictive — “the returns policy is 14 days” is mentioned by a buyer specifically because she discovered the metallic taste only after the return window had closed. 

❌ Customer service described as unhelpful on coating and taste complaints — “contacted customer service who said I must have put it in a dishwasher which I had not” and “they were incredibly dismissive” per documented 2025 accounts 

❌ Yeti specifically outperforms Frank Green on coating durability per a direct comparison — “I have a YETI which has lasted over a year without a dent or scratch. Frank Green paint doesn’t [match this]. I’ve sent pictures and a warranty claim — their answer is that the bottle is still useable and paint isn’t covered.”
