Cellular Blinds (Group Buy earlier this year)

[imported_j_z]

Hello, for those who bought cellular blinds through the group buy (or other means) earlier this year, could you share your experiences of them? In particular, does the room darkening feature really make the room dark (even during daytime), ie, is it necessary to turn on lights? Does the light filtering feature provide enough privacy at night, ie. could people easily see what is happening in the room through the windows?

Also do you think the top-down bottom-up feature is useful?

Thank you in advance!
