kingston (and sandisk) memory cards are good. I've been using their products for more than 20 years, and never encountered any card failure. Moreover, I do care about warranty (especially for those with lifetime warranty). And I would only go for hong goods from reputable distributors like supply consultants, viewking, GC, etc. Of course, if the price is extremely low (such as buying something during travel), warranty may not be a matter of concern (assuming no warranty at all).
