If you have a computer or a laptop then chances are that you own at least one USB stick. Most people just go out and buy the cheapest one they see but there a few things you need to look out for, like size, speed and what it is compatible with.

This is a very small USB stick, both physical and memory wise.
Being this small makes it ideal as you don't need any room to store it and it will fit in your pocket. But obviously being the size it is, it can get lost rather easily.

It has 2GB of memory which is all you need if you only use it to store things like word documents and small excel spreadsheets, but if it is for something bigger like applications, a bigger one may be needed, or you can buy an external hard drive. But external hard drivers are much bigger and won't fit in your pocket, but they do have much bigger memory.

USB sticks are easy to use, simply plug it in to your computer or laptop using one of the USB drives, it may install some software which will take a few seconds are its ready to use.
Simply drag and drop your files onto the memory stick or drag and drop files from the memory stick to your computer.

Most USB sticks come with security features, which this one does.
They are simple programs that you can set up to ask for a password when it is plugged in, which is good because if you loose it, no one can gain access to it, but these can be hacked quite easily. You can download better ones from the internet that you can use.

This is a very good USB stick and is all you need if it is for storing small amounts of information.

The one thing that annoys me about it is that the cap can sometimes fall off quite easily.
