LinkSprite Wifi Shield

Has anyone used this Wifi shield?

I am new to Arduino, and microcontrollers so I am not sure if I should try to use it without any documentation.

I have ordered a Asynclabs Wifi shield but its on backorder so was looking for alternatives. Should I just wait for it?

Here is a link to an ebay item: http://cgi.ebay.com/LinkSprite-WiFi-Shield-Arduino-/270640434787?pt=LH_DefaultDomain_0&hash=item3f036d4e63

And here is a link the module its using: http://www.linksprite.com/product/showproduct.php?id=26&lang=en
