A little is OK



Only 5 minutes in the gap time, just 1 minute before going to bed

When an idea pops up, you can start right away and put it away in no time. I can come up with ideas at random times like before I go to bed, so I'm quite grateful to be able to come up with serious ideas for just one minute. Of course, it does not emit blue light, so you can use it before going to bed.
