Thanks for the link..
May just apend some money to try it out
Where to buy this? At least not available in shopee or lazada.
Anywwy this is with the earphone jack and transparent disk plate? Not very convenient le
Therefore my question lo, where to test them out..
see from YouTube review, Adonit is rubber tip, which may be some thing i m considering...

Your customer? What do u do?

Don’t see the option to connect with lightning port for sonarpen..
But with cabling when drawing, don’t think it is very convenient.
Never consider upgrading?
