Pros: Fit with ease into my Lenovo tablet, no issue with the extra heat spreader. My windows xp recognized the memory with no issues. There is absolutely a rippin' fast difference between not having this memory and having it.

Cons: None so far.

Overall Review: I was a little leery about buying these gskills due to the fact that a couple of people commented on the extra amount of space the heat spreader takes up. I first checked my laptop memory module bays and saw that mine were set up one next to the other instead of the traditional one on top of the other (or the one under the keyboard and one under the laptop.) I didn't have to make any adjustments at all, these babies just snapped right in with no issue.
