Unfortunately Onyx Boox have used sockpuppets and other dirty tricks on Reddit[0] and elsewhere to harass and deter users reporting broken screens. Their international partners have webpages explaining how it's "impossible" that e-ink screens can be damaged or broken without you dropping or sitting on them[1] And in general the company is hostile to anyone with damaged devices or issues of other sorts.
Although no-one is perfect, I really like Supernote and their way of developing as much as possible in the open[2]. The devices are really great to use[3]
