let me know if they’re worth the price, been looking for an ereader tablet that has a long lasting battery - currently have a oukitel rt7 titan, the thing is a fucking BRICC (something like 2.3kg I think) but hey, its battery lasts literally weeks (28ish hrs ScreenOnTime, but thats about 17days of usage for me)

have you looked at the color e-ink tablets? A cursory look reveals the boox air3, which might be a good fit for your use case
