Flawed - ink jams more than it flows
on October 25, 2015
I've generally been a fan of the Pentel Energel series, but these pens have proved to be unreasonably frustrating. Perhaps I got a bad batch, but my experience is that the pens will write for a few seconds, and then the ink will clog/jam/dry up. It takes 10 seconds of scribbling to free the ink before I get 5 seconds of writing. I could understand if this happened in one or two pens, but of the box of 12 that I purchased, every single pen has exhibited the same problems. I've gotten to the point where I've thrown out the box; they're absolutely worthless to me.
