Way too long, 2 months.

The super diffuser lives up to its product description. It has a beautiful design and can operate for 5 consecutive hours with minimal noise. It arrived within 3 weeks, and the scents it diffuses are pleasant and well-dispersed. The fragrances are not overpowering, even across the room. Overall, it's an excellent product!

The item matches the description, arrived safely due to good packaging, and is very stylish.

The item has a problem. It turns off after a short time.
