Very often in other devices the precision in the detection of the place i was putting the pen and my own perception about where i was putting it was very dissapointing

I want it to do some sketchs so i miss a lot the ability to erase part of the screen and do not have to erase it all

It is not the case with this little device so i think it worths the money i spent

I have tried to do sketches in other devices but i never got an optimal feeling
