Having known Dan for a few years, and having essentially the same return policy myself, the bottom line is that it's all about the company behind the policy/warranty. The same is true regardless of the size/type of company.
I can say that at least part of the reason that we've only had one set of our speakers returned (because they just didn't make the customer's Jell-O jiggle), is because we bust our back-sides to make sure that you WANT to keep the speakers. That said, rest assured that things do slip ...
What Mike and Dan are saying correlates just about perfectly with my own experiences. Sometimes it's a sticky business, other times it's really smooth sailing all the way.
I think it all boils down to the people and their business philosophies; if they are sound, no problems are expected within reason, but if not, there will be problems.
Some months ago, I spoke to three local manufacturers about this, I was sort of curious. One said he had had several (unspecified how many) requests for reurning the goods, and since they were returned in perfect working order, their warranty stimpulates that the customer is charged with shipping back costs. I was told that before they introduced that clause, more people simply played around, ordered it, tested it and had it shipped back; after it was introduced, the level of such players decreased drastically in favor of serious customers. The problem is compounded by the fact that they sell all around the globe, so shipping costs are by no means small or gentle.
The second said he had had only one return for not at all cheap products, and that one problem was a bad case, because the unit had been returned seriously damaged in an original undamaged shipping carton (a large, deep scratch across about 2/3 of the front plate, one side hit with something REALLY heavy). The customer played stupid, made it look like the unit tried hara kiri all of its own accord. At that time, the debate was still on, so I don't know the outcome.
The third said he had experienced no praticular problems, a few units were returned, money was sent back, and that was that, no big deal.
But this made me think that just as there are all sorts of people offering 30 day money back guarantees, so there must be all sorts of people trying to benefit from such guarantees, from honest-to-God customers to bums of all sorts.
Stands to reason, really, when you think about it.
