I’m not surprised these are on sale now that the apple pencil has taken over the market.
Quite a few companies were making capactive stylus, many even offered pressure sensitivity, and Apple steam rolled them with not much notice. Apple has a history of doing this though. Sorry Adonit, Studio Neat, Adobe, Wacom, Fifty Three, Ten One, HEX3, and all the rest!
Since Apple never provided a stylus API up until now, all of the previous pressure sensitive stylus required app developers to incorporate special libraries and required app/stylus pairings. This Adobe stylus only works with 3 adobe apps all of which also have apple pencil support as does any art app that has been updated recently.
I’d still recommend this stylus to people with older iPads, except this one only works on iPad 4 or newer. The best pressure sensitive stylus for older iPads by a larger margin is the Jot Pro by Adonit.
They have a very narrow window to unload all of these.
