Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

Let me give you an example: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.
The answer to this example can be: Positive Review
Here is why: This rating is correct based on this review provided by the user as they liked the product very much and they were surprised that product is so good.

OK. solve this:
My ancient machine was feeling strapped for memory so I went looking for an upgrade. I'd always had good luck with the few PNY products I'd purchased before so with that experience and the excellent rating here at amazon I purchased these sticks.<br /><br />I tested the memory with Memtest 86+ for 72 hours just after I installed it so I thought I'd be safe. One month later the system starts to be unstable, I tested the disks and found file corruption (which meant my backups were also corrupt.) I did a short Memtest (2 runs) and had no errors shown. However pulling and testing the disks on a different system had the disks themselves test out perfectly. So I went back and ran Memtest again and low and behold I had intermittent errors that always occurred at the same location but might take up to 8 hours to show up. Unfortunately it's just a few days too late to return them to amazon.<br /><br />Note: the memory was set up at stock (auto detected) settings, no overclocking on cpu or memory.
