Really good, top quality unit. I got this recently to go with 65 LG C1 and I have not been disappointed at all.
I'm yet to fully tweak the settings on mine - I am waiting until I can get some speaker stands, but the fact that it connects to the Samsung SmartThings app is handy.
Three things to keep in mind with this model:
1. It is a beast, the soundbar itself is one of the biggest I have seen so make sure you got room.
2. It does not come with rear speaker stands, and unfortunately Samsung don't sell any so you will have to find 3rd party ones (if anyone has any good recommendations, I am all ears).
3. You will not be able to use the Q-Symphony mode that it advertises unless you have a new-ish Samsung TV. But I didn't care too much about that, I always find TV speakers too 'tinny' anyway.
I know that TGG Commercial needs membership, but you may be able to try price-matching or negotiating at JB/TGG. I have been able to do this before I had access to the Commercial website.
