Summary: I used this a few times at home. Then I took it to work. Inserted it fewer than half a dozen times. The plastic tongue inside the metal housing slid back. Computer doesn't see it. Luckily I didn't have data on it, but it wasted my time.
Excerpt: I needed a large quantity of flash drives - the PNY were just what I needed at a great price plus free delivery over $49 - they arrived in just a few days. It appears I have one defective drive out of 20, but I will call customer service. Always satisfied with B&H.
