OK so I screwed up my first post ... this is for Rob C - don't touch the bottom. I don't get the tingle from mine.

And for everyone else who has an issue with Apple "stuff" - if you want a Cadillac, you pay extra. Pretty simple. I've been using non-Cadillac equipment for the past 30 years. I finally made the switch and wonder, as do most switchers, why I waited so long. Cheers
