This is not an every circumstance attachment medium. Meaning, you can easily go and work out like an animal sweating profusely, with the only downside being that the stuff will run & mix with your sweat, so you'll need a forehead wipe, but it will dry back to a strong attachment.
You can't shower ( on the hair) or swim with it, and I wouldn't suggest going without an umbrella in a rain.
But, if you're not doing the above and want a rock solid attachment that you can put on in 2 minutes & take off in 45 seconds, this is it. With a spritz of water + Wax Works, I've had 3 solid days with zero lift. The trick is to a) put it on a tad thicker & press in a tad earlier than you would glue then b) have no overhang of edges into your real hair, so contact area of the unit is all on your shaved area. Attaching the full area gives such a tight grip that you don't get the tourque points at hairline that you get with just a perimeter attachment, so, no lift.
