I like the idea of the product but after sundown frankly it could be replaced with a 20 cent piece of plastic.

  > it could be replaced with a 20 cent piece of plastic. That's not a terrible idea... Are there any cellphone cases on the market that would make swapping out such a piece of plastic sufficiently straightforward?

    Our local astronomy club just gave out red celophane plastic bags. You could probably use a sheet of that (which looks to be about $15 for a package that you could cut yourself?), and keep it on your nightstand. I know it's neither as convenient nor as easy to use as a case mod or f.lux, but it's worth a shot.

    Someone could probably make it work via a manual mechanism built into a case -- a loop of transparent film through the case, filtered on side of the loop, with some sort of locking mech to pull the moveable filter tight against glass during usage.

  That's the point - you don't have to carry a piece of plastic around with you. Also the effect appears gradually.
