We purchased a variety of honeycomb blinds (double & single cell and with and without day-night). They were all very easy to order and simple to install.
We're really pleased with the look of the blinds and the ease of operation.
I had my doubts about the block-out portion of the blind dropping to the bottom of the sill during the day but they are very compact and this allows us to partially drop them to let in early morning light while keeping privacy.
