wow that must be torture, running out of a pencil in the middle of a drawing assignment for a client.

The truth is it is difficult to use pens that are not compatible with the tablet, either the drivers, the operating system or simply because the pen was not given the courage to cooperate.

It's great your experience, greetings and the advice is to have more than one of these pens, so it is better to have it in case of emergencies such as this one, to complete a customer order.
