EMS/TENS/MSG Device - Anyone tired?

I have a TENS device on the way. Has anyone ever tried these for ED? If so what would you suggest for pad placement. I am thinking the perineum and the area right above the base of the penis.

Iโ€™ve tried it and I did the taint and the tail bone. If you get it placed right you can tell it works your pelvic floor but itโ€™s kinda tricky getting the placement right and figuring out the correct settings. Iโ€™d say it helps but Iโ€™m not sure how often you should do it and also itโ€™s kind of a pain to do it on a regular basis in my opinion. Iโ€™ve read that it works though. Good luck!
