Good both directions
Started the day by accidentally brushing a goat-head thorn out of my tire and the Stan's wouldn't seal the resulting hole so, lacking any glitter, I had to break it down, throw some coffee grounds in there, and recharge with Stan's. Worked like a charm and pretty easy since I was still only 100-feet from the air compressor.
Also had a pretty quick ride home with no noticeable tailwind. I think the ECR on Knards is faster than it looks.
