I own over 20 plugs and this one wins the #1 spot. The weight makes a huge difference! It reminds you that it is there.
I was concerned that the steel, being so rigid and inflexible, would be hard to insert, but it was very easy (though you might want to keep that in mind if you are an anal newbie).
Stainless steel is a great material for anal toys because it is non-porous and can be sanitized in a variety of ways-- soap and water, dishwasher, boiling-- you name it.
As far as actual use goes, this is the first plug I found I could wear for very long periods of time. Other plugs I could wear around the house and for shorter periods of time but I have worn this one out to dinner, to the movies, in the car, and once, even to bed all night. I experienced no discomfort!
It is also great for double penetration and does not get in the way of my partner penetrating me. The handle keeps the plug safely in place and does not allow it to slip too far in and also makes removal easy.
I highly, HIGHLY recommend this plug!
