I found that it seems to depend on how well the pharmacy did at getting air bubbles out, how well it was mixed, and also the cream base that was used.
I received one topi-click where it seemed that the cream was almost foamy, I'd turn 2 clicks and it would take about 10 minutes for all of the dose to come out. A real PITA.
I used to like topi-clicks, but now I miss the days when I used to get t-cream in syringes.
