"I have fallen in love with the DOTS line and thought I would try out the gel pen just because. But I wasn't expecting much because inexpensive gel pens generally just suck.
My surprise how awesome this pen works as a writing device. It actually glides on the paper, you can see the color, and it doesn't smear. I have been using it with the Dots diary. It has impressed me so much I am buying the 5 pack and trying the markers.
The one con someone might have is the square/cube shape of the pen. Most of us, if you are an older person, are used to round writing things and the square can be little hard on the fingers.
But it also forces me to change the position of the pen in my hand fairly frequently which has been better for my carpal tunnel and tennis elbow."
