A couple of people here recommended: reviews.qvcuk.com/1690/432631/tua-tua-trend-face-neck-portable-toning-firming-system-with-demo-dvd-432631-reviews/reviews.htm
It's aimed at toning and tightening the face and neck. I can't believe I've actually bought something from QVC (which I make fun of), but took the plunge because they offer a 30-day money back guarantee.
I got dh to take some clear mugshots of me, saggy bits and all, before I started, and have used the machine religiously for the past fortnight. I turned 50 this year, but look after myself - lots of exercise and eat healthily.
Dh took some "after" pix today, and there is definitely a change for the better. My jowls are tighter, my cheeks seem more lifted and my lips are more pouty. I'll keep on using it and report back in a few more weeks.
I have been on holiday, lost about 4lb in weight and have a bit of a suntan (so my skin looks clearer), so another comparison in a few more weeks when I'm back to the stress of day-to-day life will be a better way to analyse it.
The results so far are enough for me not to send the machine back though.
