This block-out roller blind blocks out all light from outside and completely darkens your room. Wireless smart blinds darken your bedroom with a push on the remote control – and you won’t have your sleep disturbed by moonlight or be woken by the sun when you want to sleep in late. The blind comes pre-paired with the remote control and the signal repeater. For the blinds wireless functions to work, the signal repeater (included in the package) needs to be plugged in to a power socket within 32 feet from the blind. The blind is cordless for increased child safety.
