Summary: I got this to double the RAM in someone's laptop about a year ago. It's used every day and there have been no issues. I cleaned up the system and installed this stick; he now thinks I'm a wizard for making his older laptop work like it's brand new (or better). I convinced him paying about $30 is a little more cost-efficient than $300 just to surf the web. I have never had a single problem with this brand.
Summary: I installed this years ago and it worked well. PNY makes great, cheap ram and at the end of the day the computer was faster and we could open way more programs without the computer failing and getting slow.
