Has anyone purchased or used one of these devices? http://myhava.com/product_hava_platinum_hd.html?Submit2.x=39&Submit2.y=5&Submit2=Learn+More

I am currently looking at purchasing one of these devices to use at home, would be great so I could get tv almost anywhere in the house. Just wanting someones opinion on whether they are that good or not?

Thanks Laughing
