B751C S

I am well aware of the Kaleido 3 technology limits, it's just much worse on the Bigme than the Kobo. And software is abysmal on the Bigme.

Frankly, the Kobo Libra Colour can be a good option if you wanna break free from Kindle. But not Bigme. Maybe a Boox but their displays are not as good.

I own a Bigme B751CS, it's 7 inches but it's also a Kaleido screen and all the Bigme software. The Kaleido screen is very dim and requires frontlight in most indoor lighting settings. If you want to read manga, since it's mostly b&w, I'd recommend a b&w display of 7 inch or more, but definitely not

Because I wanted a device with more functions. Like TTS, like drawing on a picture, like including pictures in notes ...but ultimately the poor screen quality of the Bigme and even worse the Boox Go Color 7 gen 2 made me prefer the Kobo.

the colour is worse but i went with a bigme b7 over the kobo libra because kobos no longer have upgradeable storage. if you want to return it for something else check out this video there is a section comparing screens of a bunch of the coloured e readers. pocketbook inkpad 3 seems the best imo but
