That being said, as far as GeekHack is concerned there seems to be a 10 to 1 complaint ratio between Filco and Leopold.
Not sure if that is true (haven't done the analysis) but more than happy to accept it as a form of truth. If it feels that way to you then there is almost certainly something to it. No one is suggesting Filco is not a company making overpriced gear that is sometimes faulty. But as
tsangan points out that's a description of many (most?) companies out there.
But let's keep it real in a general sense of what to do when one has problems with a product.
How about this for an internal dialogue:
"I got a bad X from company Y and as a result if I get more products from company Y then I think it will remind me of how annoyed I was when product X failed so now I want to try other brands."
As opposed to:
"I got a bad X from company Y and therefore company Y just makes bad stuff."
The other part of all such consumer complaints is to fail to see how the retailer and manufacturer respond to the problem. Sometimes the level of customer service in repines to a problem is so impressive it makes up for the original mistake. Sometimes the process is so ugly that it makes things much worse.
If you have a bad product and the companies involved refuse to act honourably then you have a real complaint. If the OP's story concluded with, "I contacted the retailer and they refuse to help me so I think the support for Filco is bad and won't use them again because if I get another product from them and it is bad I think I will get shafted at warranty call time again." That's completely logical and sensible and damning for the companies involved.
Having a product fail and rushing to the internet to slam the company before you give anyone a chance to help you is a bad idea.
Complaint stories are far better when they include a company refusing to act responsibly, or even respond to complaints at all, or other such true badness.
Stories that are simply, "My car broke down so every Chevy ever made is rubbish and the company are communists who trying to ruin America from within, and, and, and..." don't really impress anyone or help anyone with their purchasing decisions. (Not that the OP was at that level of ranting, but was taking the first small steps in that direction.)
