I really need this item, or something similar, as psoriatic arthritis has done a number of my nails. The problem with the pens are this: starting the dispenser can be over a week-long process. You stand it up in a warm room, twist the cap multiple times, hit the thing on your thigh, repeat, repeat, repeat until finally, you get it going. And still, it is way slow and I wonder why: old product? Almond oil gumming up the works? Not sure but it is really frustrating.
