So, mine starts to break down on day 10. By day 12 or 13, I wake up with the unit sliding up a bit on the back (I guess pressure from the silk-covered pillow). It’s not the end of the world, since I sleep alone. However, it would be nice to at least get a decent 2 week hold. I use walker no shine tape and pro labs no sweat scalp anti perspirant. Worst case Scenario, I’ll just rebond every week, instead of every other week.
