I got this plug in the mail today and was excited to have a little fun with it. First I slide it in and sat on it for an hour to warn things up. I took it out to rest a bit before inserting it again to head out to dinner with friends. They never knew it was in the whole time! Almost three hours later I'm back home and here we are. I especially love the way this plug easily stays in place. It's a nice plug when you want to know you've got one in for comfortable wearing but not too big to be awkward in public etc.
