Added the Graywind Motorized Shangrila Shades recently. Turnaround time on the order was quick.
Install was easy, they look great, sync with Alexa was easy (we love this feature). I've read some reviews where some couldn't connect the smart blinds with Alexa. If you first use the Graywind app, it's effortless. Takes only a minute. Commands "open", "close", or "set blinds to 50%" or however far you want them, is so convenient. With the Shangrila Shades, they have the added feature of flipping to an open position when all the way down, which provides filtered light. We've found that the command "close blind" will bring them all the way down and then flip to this filtered light position. However, "set blind to 95%" brings them all the way down but leaves them in room-darkening mode. The Graywind app is nice. Slide the image of the blind to whatever position you want. We did get one remote too. Everything works, and looks, as hoped.
We did not go with solar charging since our cords could be hidden and plugs were conveniently located.
