Does anyone use a Rocketbook? How about kids using them at school?

I briefly looked into them this summer thinking it would cut down on how much they need to carry daily, but I just wasn't sure. They do not have lockers this year and do have Chromebooks in bags to carry. They only have 3 classes a day, so it's not too bad bringing the right notebooks, etc, but I wonder if a Rocketbook or similar would be good. It looks a little bit of a pain to have to use a phone to get the documents to Google or someplace else, but I imagine kids for sure would get it easily enough.

Many are on sale 25-40% off on Amazon now, so I'm looking again.

DD is a paper lover, so I'm less sure about her. The boys read e-books and type notes when they can, but both need paper notebooks for class, so I wonder if they'd like these instead.
