Introductions discussion

Hello everyone. While I’ve been around chastity for a while, this is my first time joining the community here. I’m hoping you all can offer some guidance. My Delectable Discerning Domme has decided it’s time to swap out my CB 300. We’ve scoured various websites and Tumblrs, and she picked one (though she hints there might be a few options since she wants me rotating through different devices) which is pictured in my avatar. I’m going to upload the image here too. We were really drawn to its elegant yet simple effectiveness. Sadly, we only spotted it on Tumblr. The link seems to lead us here

However, I’d love to know if anyone has actually used this specific device or can point me toward the exact model shown in the photo. Any assistance would be greatly appreciated. We’re keen to get her into this upgrade as quickly as possible. bitch c 34 days remaining in a 100-day denial
