And it was remarkably nice! Prior to this I was using a 29g half inch and that was fine... but after one shot with a 31g needle, it felt like nothing going in! Also, my one concern was that it might be slow to move through the small needle, but it was not significantly different really.
This was all subQ as well.
(And when I look at those 25 gauge needles that I used to stick in my leg... it's almost frightening now how big and fat they are, lol. These smaller needles have been nothing but improvement over those old lances.)
Just wanted to share this positive experience.
