Honestly, I was skeptical about the Bluetooth part, but the motion sensors give me real-time feedback that keeps me aware of how close I actually am. It's made my practice sessions way more deliberate, and I've noticed a real difference in control during actual intimacy.
The motion sensors actually track my pelvic movements in real time, and that feedback loop has made the control drills far more precise. Bluetooth setup was a pain at first, but once it connected, the whole session felt more intentional.
