Birdlocked discussion

I’m planning to test out a birdlocked mini device. I’ve come across both positive and negative reviews about them. My balls are on the larger side, but my penis is small when flaccid, so I chose the mini model; I just hope it fits well enough. We’ll see what happens. Since it’s made of silicone, I figured it might be a good choice for someone active like me…Has anyone else used one? I work out every day as part of a medically supervised weight loss program. (I’m hoping to lose enough weight to compete in my age group for mountain biking, but time will tell!)
