I'm sorry they've got you believing it.

I guess if you spend enough time and money getting products from companies that make defective products and only give you 30 days, you start thinking it's normal. You purchase something and notice the defect 40 days later, you just shrug and blame yourself for not returning it earlier.

It's not difficult for a manufacturer/brand to warranty products as long as they're of high quality to begin with. Take REI for example. Any of their branded products are guaranteed for life. I bought a tent from them in 1997; practically lived out of it for a year or so. 20 years later, the zipper wasn't working very well, so I contacted them to find out how to get it fixed. They replaced the tent at no cost.

Even if it's just a reseller of other products, if they are quality products and they company cares about their customers, they can offer fantastic warranties. An example here is Sweetwater. They sell musical instruments and accessories. With very few exceptions, they will replace anything defective for up to two years. Even their used gear is guaranteed for 90 days. Think about that. It's _used_ musical equipment guaranteed for 3 months.

So the only reason I can see for only having 30 days warranty on something like a USB cable is that they are aware that their products are low quality and the only way they can stay in business is to avoid having to deal with their faulty products. When a company does this, I feel very comfortable calling it a scam.
