Dr. Grip was one of my first loves. The pen came in PURPLE, and it was big, fat and showy. I still have a soft spot for the Dr. Grip, but the Rollerball is not my favorite. The line width is solid, but the black is pale and comes across grayish with an uneven line that fades in and out despite pressure. There seemed to be a noticeable feeling of drag when writing. The Dr. Grip does well with small writing, so those with accurate, tiny writing might want to give this one a go. I personally love the ergonomic grip and that the Dr. Grip is retractable. Overall, the Dr. Grip gets a 2/5.
