Why the Dolphin Pen is better:

•If you wanted to have the same levels of portability and mobility as the Dolphin Pen from another thumb drive screen reader, you would need to not only carry your thumb drive but also your USB dongle for product authorization. Not only would you need to carry two USB devices with you, but for the screen reader to function fully, the computer would need two spare USB ports. With the Dolphin Pen the authorization is present on the Pen, and so you do not need the full product installed or authorized on the individual computers and you do not need to carry around any additional ***authorisation dongle***.
•The Dolphin Pen includes patented anti-corruption protection, designed to help protect your software and your computer. Each Pen produced by Dolphin has been quality assured and guaranteed to be safe. The last thing you want is for your access software to malfunction or even worse to adversely affect your PC or network settings. All Dolphin Pens come with Dolphin’s free lifetime technical support.
•Beware that USB thumb drives vary greatly in quality and integrity, if you decide to use your own thumb drive and download a screen reader onto it from the internet, there is no guarantee that the device will not be corrupted. Whilst it appears that users are being offered greater flexibility in the type of thumb drive they want, by being able to buy their own and then download a screen reader, there are many low cost USB devices and many imitations available for purchase; all of which offer no guarantee against corruption.
