Chromecast Feature is awesome!
I bought this to add to my Google TV and whole house Google speaker system. I tried a couple other sound bars that were compatible with Google TV but each had their issues. This worked seemlessly!

Great Soundbar
This rivals any sound bar I have heard and I've listened to some pretty pricey versions. This is a great buy!

I bought this sound bar because of the reputation that Polk has. Sound is so-so, not quite what I was expecting. The speakers on my TV went out and needed something to broadcast sound. I listened to the speaker in the store and it sounded good (as it always does, and not in your home). I asked the sales person if there was a way to boost the bass coming from the subwoofer, he told me that he was sure it could be done. Sound is good for the high to mid tones, but if your looking for a subwoofer that gives you the deep, rumbling, and thumping sound, this might not be the best choice.

Worth it
Was delivered quickly once I straightened out a billing issue (and they were very helpful with that too). Easy set-up. Sound is A W E S O M E!
