1 out of 5 eggsPretty useless

Pros: Technically you can load the device driver (Win7) and get Windows to recognize the USB ports of the card.

Cons: Useless after that... I'm guessing its due to ExpressCard specification but the USB ports can't even power a memory stick or externally powered USB drive. That makes this device completely useless unless you also purchase a separate 1.3mm 5.4V, 2A DC power adapter to provide power to the USB ports. I couldn't even get a mouse to run off the ports. Very lame...

Other Thoughts: Manual states "built-in DC Jack connector for receiving extra power to meet USB 3.0 +5V/900mA power output standard." My testing found no USB devices are going to work with it unless an external power supply is provided.

Manufacturer Response:

Dear customer,

This card is designed for easy installation and fast performance. If it is not working with a mouse, it might be a defective product.

Before you contact us for customer service, please check the following:
1. Check the device manager, make sure the card has been installed correctly
2. Check the inserting of the Expresscard. Make sure the card is firmly inserted into the laptop slot

4 out of 5 eggsIt works...but

Pros: Works as advertised. Better speeds with external hdd.

Cons: You need an external power supply to power the card if you want to use an external HDD. (not included)

Other Thoughts: On the over view it makes no note of the fact that you need a power supply to make it compliant. You have to dig deeper to find that.

"Built-in DC Jack connector for receiving extra power to meet USB 3.0 +5V/900mA power output standard"

Still gave it 4 eggs, I should have read more... but its still going back, I wanted a cleaner solution than this.
