They mention "reMarkable Paper Pro", but I'm not willing to pay a subscription for such a physical device that already is quite expensive.
I see reMarkable says[1] you can use it without a subscription, but I'm not confident they won't pull the rug under my feet.

The remarkable team is good at marketing their product, and of course they’ll get it “calm certified” if they can. Keep in mind there are plenty of alternatives to it (boox, supernote, kindle scribe, many more). I bet you 90% of them are just as “calm” as the remakrable.
