In today's article about the success of Mike Lindell and his MyPillow product, I mention that the pillow has a 60 day money-back guarantee and claims to reduce snoring, migraines, insomnia, neck pain, sleep apnea and fibromyalgia.

First, a note about the guarantee. Consumers have complained that when they try to return the pillow they are encouraged to try a different fill amount instead. The company offers a "white" version with a medium amount of poly-fill, a "green" version with slightly more and "blue" version with even more. So if you want to return the pillow because your medical problems haven't subsided, the company will try to exchange the pillow until they get it right.

That's a reasonable strategy, but what some cosnumers have discovered is that the 60-day warranty doesn't re-start when you get the replacement pillow. In other words, if you return a "green" premium pillow for a "white" one after 45 days, you're fine. But if you decide to return the 'white" one after 20 days, you will have exceeded the 60 day limit and you will not be eligible for a refund. Bottom line:Do all of your exchanges within 60 days, or you won't be eligible for a refund.

Ironically, many of us who may be unhappy with the pillow because it didn't solve our medical problems won't bother returning it anyway, said Vladas Griskevicius, associate professor of marketing at the Univeristy of Minnesota Carlson School of Management. "Most consumers are too embarrassed to to return a relatively expensive item, especially if the product makes medical claims," he said.

Griskevicius said that MyPillow's comparatively expensive price ($50 to $90) makes consumers tend to believe its benefits. "If it only cost $20 no one would believe its medical claims," he said.

Most of the 20 readers who contacted me after a Facebook inquiry liked their MyPillow. A surprising number also said that it didn't live up to its medical claims, but that they still prefer it over the other pillows piling up in the closet.
