i've always liked my Birdlocked Mini - the comfort of the silicone cage has been unrivaled. And the Strict Gate features the same cage as that Birdlocked Mini. What i have not been particularly fond of in the Birdlocked Mini is the ring, and the modified hose clamp used to hold everything tight. I find that one or both testicles can retract too easily through the ring, even while locked.
When it comes to ring shapes and perceived security, i've always liked the Holy Trainer chastity device rings. They fit comfortably and are contoured nicely. Strict Gate has taken the Holy Trainer ring (and lock assembly) and mounted the Birdlocked Mini cage to the Holy Trainer ring. The soft silicone cage includes the tab of the Holy Trainer cage that extends back underneath the ring. The soft tab, however, is more comfortable that the rigid tab of the Holy Trainer. This promises to be a very comfortable combination. Time (and only the test of time) will tell.
Speaking of promises, the Strict Gate chastity device includes a pledge ring but the pledge ring can be exchanged for different alternative rings: a tiny pico ring, a glow in the dark lumino ring, and an enforcing stricto ring (reminiscent of the points of intrigue teeth that could be inserted into a CB6000). Some day down the line, if i like the Strict Gate device enough, i might consider trying the variety of pledge rings. For now, i'll give this a try and see how it goes with an extended trial period.
Off to see how things go.
