I've used the Norelco w/ lotion and one of the high-speed Panasonics in the past. But haven't used them since I started shaving again in May.
A couple of weeks ago, I dug them out and tried 'em ... but got a lot of irritation and some bleeding.
My best luck is with the HeadBlade Sport. For a quick shave and minimal irritation or bleeding.
I suppose if I used them more consistently, my scalp would adapt to the electrics again.
