What to know before buying
Listing details to confirm
The listing gives conflicting battery quantities: the specifications say 4 AA batteries, while feature text says 3 AA batteries and states they are not included. It also labels the lights Bluetooth-connected despite describing button operation, and the title says blue while the listed light colour is blue and white. Confirm these details for the selected item. The 6-hours-on/18-hours-off timer and IP44 protection are listing claims, not independent verification.

Customer feedback highlights brightness and ease of use, while reports on quality, reliability, colour and durability are mixed. Battery life is a specific concern, with some customers saying batteries do not last longer than a week. Those concerns matter for a 40-metre battery-powered set, especially if you plan to leave it lit for extended periods. The rating distribution is mostly five-star but includes a notable one-star share, so overall ratings do not erase the reported variability.
