I'm OBSESSED with the format of this planner. It's been impossible to find something that has some structure, but is still flexible enough for my needs. I also hate that so many planners don't have full weekends-- some of us work on the weekends and need the full space to plan! This planner has the same space for every day of the week. I wish the hours in the vertical planner could be customized, but at least it goes to midnight. And the horizontal is perfect because it has ample spaced in the non-gridded section for my appointments. As someone who has up to 7 meetings a day, it's SO HARD to find a planner that has enough line space to write out that many meetings. The paper is also great, and I love that the margins and boxes in the calendar are the same 1.5" of the Erin Condren vertical planners so you can use the same functional stickers as well as full boxes in these.
So what would I improve? I would really love it if there was a pen loop as well as a second ribbon marker. Especially because there are TWO notebooks inside, having an extra page marker would be ideal.
