My kingston SD cards is from a B&M store, and they have been working fine in different hardware.
My RAM in the computer is Corsair, and my SSD is a OCZ, just had one of my 8 GB RAM modules die, but the other 3 work fine.
My worst experience with memory was the 32 Gb lexar Sd card who died before it had been thru 1 cycle, but the RMA on thet SD was a joy.
Allso the watercooled OCZ RAM i had in my computer before was a let down, the modules died 1 by 1, but other than that i have been using OCZ RAM for years in fairly overclocked computers without any problems.
Not super agressive overclocking, mostly on watercooling rigs, but i have been known to break out my fin tipped soldering iron and solder on motherbords and GFX cards to free more performance
I have used kingstol RAM in computers i have build for other ppl, and i have never heard of any of those die, and often it have been ther cheapest Value line.
