Onyx Boox Note Pro - standing cover?

[PiotrK]

Hi,

I'm looking for a cheaper version of newly released "standing" cover? Something like this https://shop.boox.com/products/boox-...-case-for-10-3

I know there are non-standing affordable covers like https://www.amazon.de/YuanZhu-Leathe.../dp/B07PTBZKHP

I also found a standing cover from Jingdu https://www.amazon.com/Jingdu-Origam.../dp/B07NKKWGQ8 but it's not much cheaper. On the plus side, it seems the stylus holder is better placed than in the original.

I also found a standing cover from Reboon https://www.amazon.de/reboon-eReader.../dp/B07QLZY1XJ which is cheapest so far, but the customer review says that something related to magnets is problematic (I google-translated from german to english and it was a bit broken translation, so I might be wrong).

Anything else?
