A:Answer Yes. There is a significant enough amount of lag to notice it, but it doesn't affect the use of the pen. It is functional and does not feel unnatural while writing or drawing.
The cons in my opinion:
*needs to be recharged (battery operated).
*the cap is magnetic, but loose so it can be easily lost.
*it can be charged in the tablet or via cable, but will require a separate cable if you wish to charge both at the same time.
