Just a note: The EU consumer protection directive requires all countries to provide an at least two years long consumer protection, which many countries implement by requiring a standard two year warranty for this kind of products.

But not all counties in EU are equal. Some do it better. Finland, for example, has this protection defined in a consumer protection law, which has nothing whatsoever to do with a manufacturer warranty or any claim by the manufacturer. Instead, the seller of goods has the responsibility for a device to work as long as is reasonable to expect it to do so. In a clear design or manufacturing error, this law-based protection will last for years. For example, a phyical USB interface should work for many years, not just a year, as probably a warranty might imply. And after all those years, the seller of the device is the party responsible for the issue.

And of course, the seller, manufacturer, or anyone else can not decide that a functionally different or inferior product would suffice as a replacement.

And If there are discrepancies, a court is not the first step (who would really bother?). Instead, all municipalities are required to employ officials who help people with these matters.
