Furthermore, it comes with a set of 10 different 100% pure essential oils, providing a wide range of scents to choose from.

However, there are a few drawbacks to consider. The power source is corded electric, which may limit placement flexibility. Also, while the dark wood grain design is aesthetically pleasing, it may not match all decor styles. Additionally, the diffuser has a coverage area of up to 300 square feet, which may not be sufficient for extremely large spaces.

The automatic shut-off feature adds a layer of safety, ensuring it will turn off when the water runs out, so there's no need to worry if you leave it unattended.

However, there are some drawbacks to consider. The 90ml capacity means it may require frequent refills for extended use, especially if you're utilizing the continuous mode. Additionally, being corded means it has to be placed near an outlet, which could limit placement options. The included LED light provides a gentle glow, enhancing the ambiance, but some users may find it unnecessary or prefer a diffuser without light. This diffuser is perfect for individuals who appreciate aesthetics and want a functional yet decorative piece for their home, though it might not be the best fit for those seeking a more high-capacity or feature-rich option.
