If it's attractive because you think it would be more secure than the feeldoe, I don't think it would be. I think you'd be better off using the feeldoe with a harness like the spareparts joque.
But if you like it because you enjoy dp stimulation, it might be a lot of fun. You would still probably have to use a harness for stability. As others have said, it'd be luck of the draw with your anatomy, unless it's flexible enough to adjust itself. And I'd definitely wait until somebody comes out with a non-porous version of this. Vixen, Tantus--are you getting this?
