Master bought me the medium Njoy plug a few months ago, after wearing it for a few hours at a time I moved up to wearing it 24/7. I love the constant reminder of who I belong too. He has since bought me the large one to use for special occasions and play. The medium was perfect for me as I was new to anal. I look forward to adjusting to the large. I think everyone should have at least one in their collection of toys!
