Worked ok for me except in the front.
No matter how thin I stretched it, after a couple of showers the front tape seemed to absorb some of the water and swell up, becoming visible.
The sides and back (and front) all held just fine, however NRT tape holds just a well (I no longer use tape in the front) for how I wear and it's a lot cheaper than the ST30.
Also, as the name implies, the NRT leaves no residue at all.
The ST30 leaves a little residue (on me anyway).
So, I use NRT and that's why I use it.
