Made entirely out of silicone, this plug is scentless, tasteless, and of course, nonporous. It has an entirely smooth surface, so it glides easily and, with the right lubricant, can be very pleasant. It is an incredibly firm silicone; it doesn't have much give or flex to it, aside from at the neck of the plug. Plusher silicone is more friendly on the body, but the firmness of this helps it glide in more easily (when inserted with the right amount of lube).
The O-Ring Silicone Anal Plug is a standard, torpedo-shaped plug that has a pointed end and an o-ring at its base. It's entirely safe to be used anally, as it shrinks to a thin neck that is 3/4" in diameter. At its widest point, the plug is about 1 1/2" and it tapers to a small 1/2" diameter at the head. The length of the insertable portion of the plug is 5", and the o-ring is 2 1/8" in diameter. The o-ring's diameter is excessive, to say the least.
For those newer to anal play, this plug may not be a good first choice. It is on the longer end of the spectrum, and it is a bit wide. I would err on the side of caution before purchasing if new to anal plugs, but it isn't so large that it could not be accommodated even for a newer player.
The main issue with the size is that it doesn't seem to sit right; my girl reported that it constantly feels like it's falling out, and it doesn't ever feel "seated" properly.
The size of the toy, for my girl, was good. The shape, however, was uncomfortable; the tip of it seemed to poke in a jarring way. It did not fit into place like it should have. While it did not interfere with our playtime, it is something that I feel should be noted because it was a flaw in the design.
Another thing was that the ring was uncomfortable and awkward as well. It was just too big, even for my girl's big butt. The ring also was made of plastic. While this was price-appropriate, it felt flimsy and I had fears it would crack while we played with it. It didn't, thankfully.
Overall, The O-Ring Silicone Anal Plug performed well enough, and while it does not compare to our higher price-point plugs, it is a good plug for the price. It's silicone and the shape is large enough that it could be used by people who like a bigger plug.
Clean the toy with a standard toy cleaner, by boiling for three minutes, or by putting on the top rack of the dishwasher. My go-to method is regular soap for surface cleaning and then boiling for sanitizing. It can be stored with other toys, but I tend to put my silicone in plastic baggies just to be safe in case melting occurs.
Because it is made of silicone, it is safe to use oil- and water-based lubricants with it. Some of my favorite lubricants are water-based.
This came in a plastic packaging that was incredibly difficult to open. The paper insert did not give any information about the plug aside from saying "100% silicone." I recycled the packaging as it was not useful for storage.
