I purchased this little notebook a couple of years ago, before even knowing what bullet journal and Leuchtturm meant. Somehow I forgot about it and I never used it, but today I decided to try something new: I'm going to use it for my dailies, since it's small and portable, while the rest will remain in my bullet journal (which stays at home). I always felt the need of something smaller to carry in my bag, but I didn't want to purchase another journal, fortunately it found me on its own :)
