The eraser function that requires bluetooth and a charged battery is convenient but only works with the PAPER application that is more than limited in functionality.
Note that the full version of PAPER unlocks only when the pen is connected.
The packaging is actually nice, a mine and a spare rubber are provided.
The grip is correct, I am not an expert in the design but I did not feel any particular ecstasy.
The deluxe version is frankly not necessary especially since its magnetic side hardly lies in the Smartcover (full model known to be less magnetic than the simple model).
The mine is relatively large and when the pen is not connected to its use is my sense that less efficient competitors. In active mode it works better but nothing exceptional. See later if pressure management changes anything.
So in the end a lot of marketing, a nice package beautiful presentation videos for a decent product but too expensive.
