The world’s first app controlled chastity device. With the CellMate™ chastity device, it doesn’t matter where you are or what you are doing. You, as the keymaster, have the power to decide if your submissive is allowed to be unlocked from his chastity. In combination with the app for Android and iOS you can simply set up your account and link the CellMate™ to your user ID. Every account has a unique user ID which can control multiple CellMate™ devices. When your first CellMate™ is paired to your account the first message you see is if you want to be a wearer or a keymaster. The keymaster decides when the CellMate™ unlocks. You have the ability to change your account setting to wearer or keymaster at any time with the approval of the keymaster.Features: Worldwide control via app Keyless locking system Master controls unlocking single or multiple devices Submissive cannot cheat or escape Single player self-locking mode Real time geo location and status Long lasting battery life (8-12 months) Designed for long time wearing -Ergonomic and breathable design Available in two lengths, Regular (9.5 cm) & Long (12 cm) Two ring sizes included, 47 mm & 51 mm Made of highest quality materials IPX7 waterproof Material cage: Polycarbonate Material rings: Zinc alloy Battery type: CR 14200
