I love all the different size options available. I used the biggest size hoop and pin, and it took me a little bit to put it together; I had to look up a video, but then it was pretty easy from there; this is my first time trying a chastity device, so I was excited, I was worried it would be more complicated to put together, but it was great, fits perfectly for the biggest size ring and pin. I don’t think I’ll need a video next time I test it out. It's relatively comfortable for being a chastity device. I just wish it came with instructions so I didn’t have to look up a tutorial online.
