Pros: Upgraded fine to Win 7 Pro. I did this for the XP Mode (licensed Win XP SP3 virtual machine image) that runs in the Virtual PC environment. It allows me to continue using older USB attached hardware that is lacking Vista/WIN7 drivers. Most things work fine. The ability to run XP Mode Applications in their own window looking like a Windows 7 application is impressive.

Cons: I am having difficulty making PaperPort 11 stable in the XP Mode environment.

Overall Review: The wording is confusing for some not understanding what they are buying. This is a License to upgrade an existing PC running Windows 7 Home Premium to Windows 7 Professional. You need a high speed link to go to Microsoft online and effect the Upgrade.

Pros: Works as described plus automatically installed drivers when first inserted into my Acer laptop running Windows 7 Home Premium 32-bit. Locks into slot securely.

Cons: None at this point.

Overall Review: Shame the manufacturers of laptops don't build eSATA connections into the PC rather that having to use an add on ExpressCard.

Pros: Works as advertised. I used it to upgrade the drive in my older Sony VAIO laptop from 60GB to 120GB. Immediately recognized and works fine.

Cons: None at this point

Pros: After reading the specifications and reviews I purchased this tester. It works for testing my older ATX power supply with a 20 pin connector.

Cons: While it works, it is sorely lacking in decent documentation. It is advertised as capable of testing both 20 & 24 pin power supplies. It takes some guesswork to figure out which way is correct when plugging a 20 pin connector into the 24 pin recepticle on the tester. None of the pinouts are labeled. I had to resort to another manual to verify the color coding on the power supply wires and match them up to the layout/labeling of the tester led's.

Pros: It works just fine in a Garmin NUVI 750 GPS. I use it for Music and Audio Book files.

Cons: None at this point.
