If you purchase an HP laptop over TV shopping networks, the likelihood of this device working with your laptop is NOT!. I could not find documentation on the HP website on what docking station to connect my HP laptop. I read horror stories of folks trying to return this.
The dock works great. I love the fact that it also charges the laptop, so there's only one cord to plug in or remove. And the power button on the top of the dock turns the laptop on, which is very convenient. The size and shape can be awkward if space it tight.
