After major issues with certain gel models of other brands with skipping on index cards and paper, I was so happy to find something that could write so smoothly and reduce the strain in my hand now that I've started bullet journaling. I've been using it so much I used up the ink in a month. What's even better, is the 0.7 and 0.5 refills are interchangeable, so I ordered a box of 12x0.5mm for the next year. This pen is very sturdy, even the threads are all metal. I'm sure the previous reviewer will find the refill will fix the damage that occurred when the tip of the pen hit the floor. It's a pity that it wasn't retracted at the time, as that would have likely kept it safe.
