As an user with experience of other e-ink tablets, such as BOOX Tab Ultra C Pro and Kindle Scribe, I have to say that I have very high expectations of the Viwoods Aipaper.
For the first week, it certainly exceeded my expectations on various aspects, such as the system design, the overlay feature, the display quality, etc.
However, within less than 2 weeks and less than 500 words writing in English, the pen fails to write when I hold it at certain angle (see attached video). The supplier says it is just normal wears and tears and refuse to follow up.
Viwoods official says the pen is not covered by the warranty (isn't it amazing that the pen that comes with the package is not included in the warranty?) and likely to be my own problem.
Although it improves after i changed the pen nib, it implies that event the metal-cored nib cannot stand a medium to low level of writing within 2 weeks. Very disappointing.
As a tablet device with amazing writing features (no sacasm, i really love writing with it), the performance of the pen (nib i guess?) and the associated after sales support are really disappointing.
I heard Viwoods are very proud of their pen design. TBH, this is not something you should be proud of.
