I have mixed feelings about Kingston Memories. The only memory I ever had fail on me was a stick of Kingston Value RAM (or some such name). However, it was on a lifetime warranty and when I called them in California they Fedex'd a replacement to me with a pre-paid (duty pre-cleared to/from Canada) Fedex return envelope for me to send my unit back to them. I had my new stick the day after I called them and before I returned my failing unit to them.
