This is incredible! You can adjust any site, with specific settings for each if you like. It doesn't need to be all dark or all light; there are in-between settings which makes this incredibly useful.Chris Ryan has used this product for one day.
Works as advertised. Works on most websites incredibly well.
Does not turn on automatically at night.
Love it. It would be awesome if we could specify a time to automatically turn it on every day.Justin Sebastian has used this product for one week.
