VlC Tugger how does it feel? Should I go for it?

I have read that the VLC Tugger creates vacuum and the “pull” comes from pulling the glans and not the skin. I am uncut and I have a tight rigged band which needs to be stretched but primary thing is to stretch.

So how does it feel from those who used it? Does it pull the glans and if yes how strong? Will I be able to get a very strong stretch? How secure is the stretch?

I want to modify my andropenis because the strap which is the only one I can use without slipping, is very uncomfortable.

So those who used if the can give me a description, opinion and what results if any.
