I am extremely disappointed with this planner. It looked like a great option for me because of the quarterly and monthly layout — I was willing to push past the issue of the extreme visual clutter of all-grid everything.
However, now that I started trying to use it, I realize the pages are completely see-through. I tested 10 different kinds of pens and even the ball-point pen is fully visible when turning the page. I don't understand how anyone would be able to use this, even grid-lovers. I spent almost $70 and now have to find a new one. Total failure.
