Even if you’re up on your legal reading, it’s likely that you missed the case of Roy L. Pearson v. Soo Chung, et al. In 2007, Washington, D.C., resident Roy Pearson hauled a local store called Custom Cleaners to court over a bungled trouser alteration that cost $10.50. “Never before in recorded history have a group of defendants engaged in such misleading and unfair business practices,” declared Pearson, who sought $54 million in damages.

His grounds? A “Satisfaction Guaranteed” sign that hung inside the store.

Granted, that’s an extreme example of an unhappy customer. But Pearson and consumers like him are a great example of why most brands steer clear of making satisfaction guarantees. Sure, plenty of retailers will take an item back—unused, with store receipt, and within 30 to 90 days of purchase; limited warrantees such as that are, in fact, typical. But companies that hold themselves to the gold standard, promising to make customers happy no matter what, are rare, notes Scott Davis, chief growth officer for the brand consultancy Prophet. “One hundred percent guarantees—no expiration, no questions asked—are the stuff of legend,” he says.

But, as it turns out, they’re still with us. Despite the rise of the throwaway culture and disposable goods (everything from clothing and technology to plastic containers for leftovers), there are those brands that still make products for keeps, and guarantee them. [To see Adweek's big list of forever brands, click here.] Among them, such venerable retailers that are famous for such policies, including L.L. Bean, The North Face, Craftsman and Lands’ End. Add to those, though, a healthy number of smaller, newer brands, among them umbrella maker Davek (founded 2005), Darn Tough socks (2004) and Bogs footwear (2002). All these companies promise total customer satisfaction, as do specialty brands like Polar Bottles, Briggs & Riley luggage and Oxo household utensils.

There is a reason so many companies are still doing it. The satisfaction guarantee, experts point out, generates customer loyalty and positive word of mouth for a brand. That said, it also offers an equal share of hassles and risks. As customer service consultant Micah Solomon puts it, “The satisfaction guarantee is a relative rarity, but with the power of social media, it can become a marketing opportunity.” Then again, he adds, “maybe it’s also marketing to people who want to screw you.”

Ric Cabot, for one, isn’t worried. As founder of the hosiery brand Darn Tough, Cabot has had an unconditional lifetime guarantee in place from the day he powered up his looms in Vermont. Darn Tough socks are impervious to holes, Cabot promises—and if they ever do get them, he’ll replace the item. (To quote the company policy: “No strings. No conditions. For life.”)

“We make the product, and that’s the difference,” says Cabot, who explains that the fad of fast fashion, coupled with offshore manufacturing, have conspired to kill off the guarantees that were once a given with consumer brands. “There are segments of the market that don’t expect—or it’s never occurred to them—that something should last more than 30 or 90 days,” he says. “In the race to outsource, to get new product into people’s hands, brands have stopped talking about guarantees because they don’t need to talk about it.”

So why does Cabot? “What I learned in advertising school is that the message is the medium,” he relates. With all of Darn Tough’s packaging and retail displays bearing the brand’s satisfaction pledge, Cabot believes his customers “empathize” with him simply for having the guts to offer one. “Customers think, my goodness, they stand behind their product, and they’re not a Fortune 500 company? It’s got to be good,” he says.

David Cook, marketing director for the Portland, Ore.-based Bogs, tells a similar story. While satisfaction guarantees tend to be the domain of long-established merchants, Cook believes the pledge has given his young company a competitive edge. “Because we’re a relatively new brand, it helps to instill trust in consumers,” he says. A promise of satisfaction removes the risk from a purchase, Cook says, meaning “people have peace of mind, and that’s influenced the perception of the company. It’s been a huge thing for us.”

Adds Prophet’s Davis: “These promises engender brand loyalty even among consumers who don’t actually take advantage of them. Just knowing that the company stands behind its products speaks volumes.”

In some cases—notably the heritage brands that have had guarantees in place for generations—those volumes have already been recorded and have turned into expectations among the public. Nordstrom, for example, doesn’t boast about having retail’s most permissive return policy because it is desperate to win customers. It’s because the store’s affluent, longtime customers expect nothing less.

At The North Face, a customer who can afford $599 for a ski jacket tends to regard the brand’s satisfaction guarantee as a given, not an extra. “We have an expensive line,” notes vp of global product Joe Vernachio. “People perceive us as a quality brand, and we know inherently that the warranty goes into that perception.”

As chief marketing officer for the 102-year-old Freeport, Maine-based retailer L.L. Bean, Steve Fuller has had the opportunity to watch how the brand’s legendary guarantee (Bean will take back any item, for any reason, anytime after purchase) has operated over his 20-year tenure. Echoing Vernachio, Fuller explains that “the satisfaction guarantee is the very foundation of this brand.”

He recounts the company’s founding legend of how 90 of the first 100 hunting boots that Leon Leonwood Bean made in 1911 were returned after their rubber soles fell off. On the verge of bankruptcy, Mr. Bean took them all back, refunded customers’ money and went back to market with a better boot. To this day, the company continues to use returned products as a kind of R&D lab.

“We go through returns with a fine-tooth comb,” Fuller says. “It’s common for us to take a bundle of returned jackets and look to see if there’s a common failure point”—one that can then be corrected on the production line.

Of course, the idea is to avoid the pile of returns in the first place, and here’s where the challenges of the satisfaction guarantee enter the picture. “If you have that guarantee and you stand behind it,” Fuller concedes, “it puts tremendous pressure on your product development.”

Not everybody wants that kind of pressure. While companies like Lands’ End make it clear they’ll exchange or refund any item at any time for any reason (“Whatever. Whenever. Always.”), reading the fine print of other retailers’ return policies reveals varying efforts to hedge the bet a little.

hosiery will never get holes.

For example, Briggs & Riley luggage will repair any broken or damaged luggage free of charge, even if an airline was at fault, but “naturally, our warranty does not cover cosmetic wear or cleaning,” its website stresses. If a customer doesn’t happen to like his Acuvue contact lenses, Johnson & Johnson will refund his money—so long as at least 75 percent of a packet of lenses hasn’t been used. And while The Snugg, a popular brand of smartphone and tablet cases, promises a lifetime guarantee, it only applies after the product has been registered, does not include clips or swivels, and is voided if the damage was caused by a force majeure, such as a flood or an earthquake.

Small loopholes, granted, but the disqualifiers of other retailers are so big they beg the question of why they even bother to pledge anything.

Take, for example, the lifetime guarantee on Rainbow brand leather sandals, which does not include wear to the sole, torn straps, damage from dog chewing, “skateboard abuse” or, of all things, “any damage as a result of the sandal coming into contact with moisture.”

something I didn't have a direct hand in making." he says.

There’s a reason for such disclaimers: those consumers who would seek to take advantage of such a policy.

“There are people in Eastern Europe—or maybe Eastern Ohio—who are crooks, who’ll exploit the system,” Solomon points out. He cites the textbook example of the shopper who buys a gently used shirt on eBay for a few bucks, then returns it to a store for an $80 credit. The ethically challenged consumer (“Those people,” as L.L. Bean’s Fuller calls them) remains the No. 1 risk of the unconditional guarantee—and everyone interviewed for this story admitted to having to deal with them. “We’ll always get those people returning the boots after having them 10 years or buying them secondhand,” Bogs’ Cook says. “It’s an obvious abuse of the policy.”

Diane Beecher, CEO of The Brand Consultancy, observes that while upscale brands tend to have customers less likely to abuse guarantees, mass retailers—Kohl’s, for example—slap conditions on their policies to keep too many people from returning lightly worn goods. “Liberal return policies are a great traffic generator,” Beecher says, “but make for some interesting return scenarios with recently used socks and jeans with scuffed knees but no flaws.”

But perhaps surprisingly, those who would seek to exploit satisfaction guarantees are comparatively rare. In the two years Vernachio personally oversaw the warranty department of The North Face, he can recall but one case in which someone was clearly “trying to get a free garment out of us”—and Vernachio went ahead and let him have it. He explains, “I’d rather be taken advantage of than take the risk of accusing a customer, which doesn’t get us anywhere.”

Naturally, eating a loss is part of the satisfaction-guaranteed game. And it may not even turn out to be a loss.

“It’s OK to let a customer slightly take advantage of you from time to time,” Solomon says. “It’s OK because you’re talking with them, and anytime you’re talking with them, you could sell them something else.”

Fuller agrees. “The small minority of people who abuse [the guarantee] ignores the vast majority of people who get it, and the benefit of treating customers the right way is that they’ll reward you—they’ll always come back,” he says.

It is safe to say that Roy Pearson won’t be going back to Custom Cleaners—and not just because he never got his pants back. The judge ruled that a “reasonable consumer” would not consider $54 million to be fair compensation for a bungled alteration job—even with satisfaction guaranteed.
