EASY INSTALL BLINDS: The remote blinds have a simple and practical no-drill mechanism(suitable for inside mount). Attach the adhesive extension block to the groove of the upper rail (it is forbidden to put more than one block), and then push it into the window frame. There is a battery compartment at the top to supply power for the shades. If the batteries are low, just take them out and replace. A stylish valance is included to block the light from the gap between fabric and the top rail..EXCELLENT SHADING EFFECT: The fabric is made of a three-layer blackout textured fabric, which is safe and durable. It is a great combination of UV and privacy protection,suitable for bedrooms, living rooms, kitchens and office areas, etc..SMART IMPLEMENTATION: The AX290 motor requires a smart bridge for APP control/voice control, which requires a hub at home, and you may try our hub. All models of Alexa and Google Assistant can be used to control motorized window shades, and can set timers and other scenes..CONVENIENT LIFESTYLE: Motorized blinds allow you to achieve a smart home at minimal cost. In the morning, when you are still asleep, the shades in the bedroom open automatically on time, and the warm sunlight spread into the room lightly to wake you up for a new day, and in the evening, when the sun sets, the shades fall on time, creating a private space for the family..SERVICE: We focus on products and service, if the fabric or components are damaged in any way when you receive the items, please take a photo and send it to us within 60 days, we will repair or replace.
