## Before you buy

- The listing is inconsistent about the connection, describing corded electric power while also listing USB. It gives a 20 m total length and separately states 10 m of lights plus a 10 m power cord. Warm white is also paired with a generic White light-colour field. The outdoor-use claim and Waterproof wording are qualified by the explicit warning that the adapter is not waterproof. Confirm the selected variant and connection details before purchase. Use a waterproof receptacle cover outdoors, as the listing advises.

## In the box

- Plug (Included)

## A good fit for

- Decorating bedrooms, living spaces, gardens or party settings where a mains socket is available.
- Buyers wanting multiple lighting patterns and an automatic daily timer.

## Less suited to

- Locations without convenient mains access.
- Outdoor installations where the adapter cannot be kept under a waterproof receptacle cover.

## Customer feedback

Customer feedback highlights brightness, appearance and outdoor use as positives, while reliability is a concern, with reports of lights stopping after about a year and a half or being completely dead. That matters for seasonal or long-term installations, even though the listing describes a timer and outdoor use. The overall rating distribution is mostly five-star but includes lower ratings, so it does not remove the reported reliability concern.
- Positive themes: Customers praise the lights' brightness and appearance and report positive outdoor use.
- Negative themes: Some customers report that the lights stopped working after about a year and a half or were completely dead.

## Frequently asked questions

The listing states 20 m overall, comprising 10 m of lights and a 10 m power cord.
### How does the timer work?
The described timer runs the lights for 6 hours and then switches them off for 18 hours each day. The button is on the plug.
### Can they be used outdoors?
The listing claims IP44 protection for outdoor use, but says the adapter is not waterproof. It advises using a waterproof receptacle cover outdoors.

The listing says to press the button on the plug to change between the eight modes.
