Summary: So far it works fine, installed in a laptop about a week ago. Did a mem test and it tested good. However, I'm not thrilled with how it was shipped. It came lose in one of the big padded envelopes that Amazon sellers like to use. No static bag or any wrapping what so ever. Also the writing on the sticker was smudged along with the sticker being torn on the edge. Seems to me that this is a used item being sold as new. I'm happy it works.
Summary: The item was dead on arrival and it didn't work at all. I tested it on two different laptop but no luck. The package was not sealed and possibly has been opened. Please test item is working or not and then send unsealed package !
