Review on PNY Attaché 4 32GB USB 2.0 Flash Drive 5-Pack - P-FD32GX5ATT4-EF, black: High-capacity storage at unbeatable value by Nicole Green

. And the brand name (PNY) is well known. Physically they are very compact and ideal for my application (photos for a digital picture frame). I only have one problem with them: the sliding protective cover is almost impossible to remove! It's a tight, comfortable fit. The device is so small that it is very difficult to lift it to separate the device from the lid. Once you've managed to remove the lid (good luck!), you're good to go. 🙂
