Can't sleep without it!
When I lived with my parents, I went to bed very early and the rest of my family would be up for a few hours after I went to bed. Unfortunately in their house you can hear everything from everywhere, so it was very hard for me to fall asleep hearing the noise from my family. I got this and it changed everything. It allowed me to fall asleep without waking up from someone coming up the stairs or making something in the kitchen. I got so used to it that I took it with me to my apartment and still sleep with it on even though I don't need it for blocking out noise anymore.
