Mystim Electric Eric?

Newbie here. Have loved prostate massage for years. Coupled with BJ/HJ/titty fuck, my wife can edge me and give me tremendous orgasms. She either uses her finger or a prostate vibrator. With the vibrator I can achieve an HFO which amazes us.

Interested in electrostim, but want to do it with out a lot of equipment and wires which would freak my wife out. Discovered the Mystim Electric Eric. It sounds pretty cool, both vibrator and estim. Anybody have any experience with it?

Thanks!
