The Satisfyer Connect App is available through iOS and Android and links through Bluetooth technology, so you do not have to struggle to adjust settings manually. People experiencing difficulty with movement and/or arthritis would benefit from the "remote control."
The Plug-ilicious 2 is made of medical-grade silicone and waterproof (can be submerged up to 1 meter deep for up to 30 minutes). A water-based lubricant is recommended with use. Cleaning this device is simple: use toy cleaner or warm water and mild soap.
