Customer feedback highlights attractive, vibrant colors and positive impressions of appearance, while reports are mixed on reliability, app usability, customization, and durability. That matters for a product whose listed effects and timer rely on its control features. The overall rating distribution is mostly five-star but includes a meaningful range of lower ratings, so it does not establish consistent performance.

Some customers say the lights work well and find them good value.

Negative themes

Some customers report that the lights stop working and describe the app as difficult to use.
