The Edge 2, and I presume their other vibrators, have a proprietary charging connection. It’s essentially just two metal contacts and a cable with a relatively weak magnet attached

I see it, 2 unprotected metal contacts. No corrosion so far? No charging problems due to defective contact?

The nice thing about silicone dildos is that you can basically just boil them for a deep clean, but I’d this for electronic ones, waterproof or not.

I don't know if you're telling me to boil silicone toys with electronics and motors inside of them or not to boil them.
