Chris,
I got my DPS in June and it really is a snap. A little down time (about a week) after the surgery, but we all need a break anyway! The whole enchilada - wires and "plug" - are very small and do not show under your clothing. The only time I notice it is if I turn over onto it in bed. When you're pacing, it feels about like setting your cell phone on your skin while it is on 'vibrate'. Very mild and after a few minutes almost not even noticeable. I zap a few times a day when it's convenient... driving to work, sitting in my office, watching tv, etc. It really is not a big deal, and if I can figure out the mechanics, I'm going to start charging my iPad with this darn thing!
It's suggested that you keep it dry in the shower and 'they' recommend using the Tegaderm patch, but I use press & seal, available in your local supermarket with the other wraps, foils and bags. Cheaper and works just fine. Good luck to you!
