I must say it’s big for something that’s considered “beginner”. It took time (and plenty of lube) to get it in and I wouldn’t even consider myself a beginner. I’ve used plugs and other backdoor toys but this one intrigued me because it vibrates. Once in, it felt great so I’d still give it high ratings but at its widest point it may be something I have to work up to. I do like it though so I’m going to look for another vibrating plug that’s just a tiny bit narrower. Great price for the quality and I love that it’s a usb charge not batteries.
