Performance - erm.
This is exactly what happened to me with Instead. Sitting, moving, squatting (!) were all risky maneuvers, and wearing a "security" pad really defeats the purpose. It was only successful when I was sleeping and my flow wasn't heavy.

I THINK I am inserting Instead correctly. I know where it needs to go and put it there. But it doesn't stay seated, it slides forward and then I have a disaster on my hands - literally!
I know I'm inserting it correctly. I can't get it any further up there! And it does come sliding back down at the least excuse. I guess this is just due to the "lay of the land" down there - 10+ pound baby in my history!

Thanks, MM, for the testing!
