The issue is that with a sample size of one (or three), then it is basically bad luck. If you get a bad unit (or a good unit) it doesn't really tell you much how reliable the other 100,000+ units are and how reliable the brand is. If you have a product get damaged during delivery, it doesn't really tell you much how reliable the other 100,000+ deliveries are.
But most people have had a problem with some product they purchased and a company that stands by things and gives no questions asked support is very valuable.
