[EX Q]: Really does a good job of pulling the dialogue out on the tv shows. Over all sound is great. Lots of available adjustments which I really like. I added a woofer and it works great with the sound bar. We are very happy with the purchase.
[EX A]: positive

[EX Q]: Good quality and not difficult to install. The instructions state to trim close as possible to the graphic as possible. If you don't their are certain places that will cause a problem. IE: around the door licks and mirror
[EX A]: positive

[EX Q]: I love the quality of the product and the nice rain shower produced by it. Including a high-quality metal extender arm was a nice plus. I also bought a valve on Amazon that allows me to toggle between the fixed shower head and a handheld one-it also allows you to split the water stream. With this setup, it's like being on vacation at an expensive hotel. The shower head will require periodic cleaning to ensure that the water nozzels are not plugged, but that takes only a minute.
[EX A]:
positive
