hi. i've worked at Office Max for almost 4 years and the K-Byte stuff doesn't seem that good. i'm basing this on the fact that we get a lot more of it returned than the Kingston stuff. of course most people probably just don't know how to install it or what kind they need. i wouldn't put any in my rig (or anyone i liked). if you really consider this person a friend than get the kingston or crucial.
