What to know before buying

Listing details to confirm

The title and product description call this a 200-LED, 66-foot set, while the listing also gives 16.5 feet per strand and 50 LEDs per strand. These figures are consistent when read across four strands, but confirm the selected listing’s strand-level details before purchase. The IP44 rating is stated alongside broad waterproof wording, so do not treat it as confirmation that the lights or battery cases can be submerged. The timer and memory behavior are listing claims, and customer feedback reports mixed experiences with timer function and reliability.
