Can the Neckline Slimmer help tighten sagging skin?

The Neckline Slimmer, a new As Seen On TV product, promises to firm up loose skin in just two minutes a day. It's a small, spring-resisted plunger that you place under your chin to exercise the neck muscles. Developed by physiotherapist Paul Younane, it claims to be "the world's first resistance toning system for the neck, chin and face." Could this $20 gadget be an alternative to plastic surgery and make you look years younger?

Dan Cassuto, a reporter for WKOW (Madison, Wis.), puts the Neckline Slimmer to the test. Viewer Betty White volunteered to use the device for 30 days. Though she didn't experience dramatic results, she likes the Neckline Slimmer and notices what she calls "a difference in her neck." Ms. White also reports an improvement in temporomandibular joint disorder (TMJ)-related symptoms: She is able to open her mouth wider and has less jaw pain after using the product.

News station WXIA in Atlanta also subjects the Neckline Slimmer to an at-home test. Following the device's instructions, viewer Angie Rodgers does three sets of 10 repetitions for two minutes each day.  When reporter Karyn Greer checks in with Ms. Rogers after a couple of weeks,  she tells the reporter that she doesn't see any difference, but that the back of her neck feels "a little sore." 

There are currently about 40 customer reviews for the Neckline Slimmer posted at Amazon.com, where it earns an average rating of 3.5 stars, which indicates that feedback is a very mixed bag. Satisfied users say it works great at tightening their skin, and some claim they look younger. Many owners, even those who like the Neckline Slimmer, say they felt sore after using it. Among the complaints, we found reports of hidden processing and shipping fees. Two users say they were tricked into buying duplicate items and were subsequently unable to obtain a refund.

The Neckline Slimmer's distributer -- SAS Group in Wisconsin -- is not listed with the Better Business Bureau. However, we did find about 15 complaints on ComplaintsBoard.com, where users report a misleading ordering process, undisclosed charges and poor customer service.

Since reviews are so varied, it's difficult to determine whether the Neckline Slimmer will work for you. If you're willing to drop $20 and give this gizmo a shot, your best bet is to buy one at a local retailer and avoid unauthorized charges.
