Some brands have a history of 10,000 sales but only 1 complain about failure while others may have 1 in 100.
Personally I feel that Sandisk being such a well known brand, definitely have their fair share of complains, but if you factor in their sales, the chances that you buy a faulty card is low. E.g. both Sandisk and Transcend has 10 complains each, but Sandisk sold 10,000 cards whereas Transcend sold 1,000. Something along that line.
Very True abt the QC , doesnt really matter abt brands for me as long it works , well some brands have Big $ to spend on the advertisment so it has it fair share on branding , even top brands fails too at time -
i have Silicon , Kingston and sandisk and photofast - each i have bought several cards before , till today it some still alive and kicking , some already died ( including the top brand )
