You will pee a lot!
If you want the reminder to drink water, this works. Someone commented on the light being distracting and annoying, of course it is, that’s what remind you to drink… I often want to throw it across the room.  My water consumption has tripled in the three weeks I’ve been using the ULLa.  It’s not fancy, it clips onto abandon if the band breaks in theory you could use a rubber band, I hair type, anything. The point is, it works.
