with no hiccupsthe Roku had some dropped connections, failure to update, but even more frustrating - even after completing the 'update' process after the 'install,' very poor connectivity and pixelation of the image - one of the reasons i returned the not-ready-for-prime-time HDHomeRun device, a real beta-hardware and software vaporware mess under OS Xthis device is pretty slick; basically you:1. plug the stick into an HDMI port2

Coupled with DirectTV Offer made it hard to pass up since we had dropped Cable about 5 yrs previous.

I read the user reviews, with the only persistent complaint being a random dropping of the wifi signal.

I purchased an HDMI extension cable (Roku's "free" extender "out of stock") which improved reception but with "low signal" indication and 'freezes' and 'dropped' WiFi connections

I also have some sound issues when trying to use headphones, the sound drops out occasionally for no reason and goes back to the tv
