The Eclipse Wristband Remote Beaded Probe is made from premium hygienic silicone, some ABS plastic, some metallic plating and stainless steel. It is all phthalate free and safe. The unit has a pair of motors, one for the rotating beads and another for the vibrating base. It also has a memory chip that remembers the last setting so you can start from where you left off. The unit is also waterproof so you can use it in or out of water. The 10 meter / 32.75 feet range wristband remote is discrete and looks like a watch with a buckle closure. Although it has a wireless remote, you can use the probe independently.The unit and the wristband remote can both be charged via USB and there is a dual charging cable included in the box. With an 80-minute charge, you get 60 minutes of run time on low and 50 minutes on high.
