Partner Plus is a couples vibrating "C" ring that comes in a hygienically sealed box. That was a welcomed sight. You have to read some small print but the packaging gives you the full run-down of features. Most notably are the body-safe silicone, rechargeable Li-ion battery, and magnetic USB charging.
As with all silicone toys, don't forget to use water-based lube. The USB charging cable has a strong magnet that will ensure your product does not simply roll away.
