What to know before buying

Listing details to confirm

The listing says the LEDs flash alternately in a variety of colours and also describes them as 14 different-colour LEDs, so the exact LED colour arrangement is unclear. Battery life is claimed as at least 48 hours for two batteries, but the operating conditions are not stated. Remove the insulating sheet from the battery box before first use, and use a small screwdriver to replace batteries. The supplied text gives no size measurements.
