nJoy stainless steel plugs are my favorites for all day wear. The Pure Plug comes in S, M & L. Don’t get anything smaller than large. I opt for the 2.0 XL. Very heavy, very easy to clean, EXTREMELY comfortable. Just don’t sit down on any chair that aren’t cushioned or you will hear a bang!
It can depend on what you're looking for. I like the weighted b-vibe plugs for a full feeling but they are skinny at the neck and not good for stretching and are very hard. Squarepeg plugs are very good quality made from a softer silicone and wider at the base so better for stretching.
I agree that the Njoy large plug is fantastic! I had a medium first and it would pop out to easily. I never have a problem with the large popping out and certainly not with the 2.0
I don't know the brand, just that they are available on Amazon. I'm wearing my favorite. It's silicone, curved with a deep bulb and the base is t shaped to sit more comfortably between my cheeks. It's the large in a graduate set, 2 1/2 wide and inserts to a 6 inch depth. The curve of the bulb sits nicely on a very happy nerve spot
