I presume you can save your notes somewhere externally, but it's not apparent from the product description. Is it doable, easy and, most importantly, reliable?
As for the previous one (single page scribble) then I found in the past that I usually have a new single page each day on my desk for tasks minor notes of that page and it's now replacing it - this is its main usage.
We only did 1 clearing cycle so far, and paper is back to practically white. but microwave was not enough, wet cloth worked better.
The paper is somewhat glossy.
