Summary: Our daughter needed a thumb drive for school and we figured this one would stand out and be harder to lose track of or get confused with others. I tested it in both a Mac and a PC and it worked perfectly. The cover stays on the drive quite snugly, at least initially - we'll see if it loosens over time. There is a little fob on the chain that you insert into the cover when you are using the USB so you don't lose it.
Summary: I thought the turtle was awesome looking at it online. When I went to put it into my USB unit in my monitor at school the shell was in the way so I had to remove the shell. If you are going to use this in a USB on a computer unit it would work fine with no need to remove the shell. I loved the entire turtle look is why I bought it. I was a bit disappointed when I had to remove the shell. It doesn't look like my turtle any more.
Summary: This is so cute! And functional, I haven't had any errors or other problems with it. I like these because they don't look like flash drives, just like toys or keychains, so I feel they're a little more secure for personal information. I think the price for what you get is pretty decent and if you need a small size flash drive it works well.
