Today my Birdlocked arrive after about a month of waiting, I got one of the last mini's on Kept-for-her. It came about 30 minutes ago and to my surprise I got it on without difficulty in less than five minutes. Used very little lube - just a touch of water based KY around the rings. My first impression is that it's kind of small. I fill it up all the way and perhaps should have gotten the regular, but it is too early to tell. It is certainly comfortable even though it keeps my ballsack tigher than the CB3K. There was never a CBXX made that I could not pull out of if I really wanted to do it, but the Birdlocked is different - no way I could pull out. I'll update in a day or so, afterall it's only been 45 minutes.
