YES! Do it. Your ass will thank you again and again!

I bought the "Pure Plug 2.0" version when EF had a sale on it. I got it about one week ago. Some might get surprised and scared by its size and weight, but I saw and hefted it at a local store (and I knew I wanted it), before I bought mine for a great price at EF.

After I warmed up with other anal toys, I found inserting the PP 2.0 easy and it almost settled itself inside my butt. "How nice," was my first reaction as I walked around with it. When I sat, I found rocking myself with PP 2.0's 1-1/4 lb mass nestled against my p-spot quite blissful.

But this mass irritates me after some time--and it's probably not good for extended wear. It's also uncomfortable lying down with it.

I think I shall buy the large Pure Plug, which is almost half the weight, and see if it's more comfortable for extended wear and lying down than the 2.0, though I don't regret buying the 2.0 and am happy with it.

To answer your question whether "the little pieces of steel really do that much," since I experienced only one of the "little pieces of steel," I'll give a qualified "yes," though I suspect all the Njoy plugs "perform to spec."

Are they worth the money? Even if you buy them on sale, Njoy plugs are expensive. You could buy a good quality silicone plug of comparable size for half the price that promises to stimulate your p- or g-spot. But you get what you pay for. Njoy plugs are good quality and you're paying for the unique feel of a mass of stainless steel inside your butt. I say go ahead and buy one. It's a "little luxury" you can give yourself. But check out the size you think you'd be comfortable with first (see: link). And you can always buy more Njoy plugs after that.

I hope I was helpful.
