Every purchase of aroma diffuser includes a 1-year warranty, ensuring coverage for any electronic functional defects or failures. However, please note that our warranty does not extend to instances such as malfunctions resulting from oil leakage due to negligence, aesthetic scratches, alterations made to the product through disassembly or modification, or issues arising from the use of alternative essential oils, including fragrance oils, concentrates, burner oils, or massage oils.
