How good is this for privacy in the day and in the night? im looking for something that offers both, but it seems that the mirrored doesn't offer night protection- wondering if this would be a better

This would more than likely be a better solution for day and night privacy. The bottom section will be solid and totally private all the time, and the top will be partially see through both day and night. Keep in mind that what you can see out in the day, will be somewhat similar seeing in at night, although from a distance it will still appear very distorted.
