Any Wireless Box Problems? - DirecTV

Anyone that has wireless boxes, in general how do you like them? Do they have the responsiveness of wired boxes or do they have any reception problems you've noticed? I'm thinking of switching from Uverse to DirecTV and have some rooms that will be hard to wire with coax. I don't mind the $99 up front since it will also give me other viewing options. Wireless can be finicky so that's why I'm asking.
