[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.
[A]: positive

[Q]: Would definitely not recommend!!! Although the actual material that the bag is made of seems to be of good quality, the zippers are cheaply made. The zippers on my bag just won't stay closed. It has split open numerous times, spilling all of its contents. Imagine the frustration having to pick everything up with 1 hand as you hold an infant with the other arm.
[A]: negative

[Q]: I bought this to use as a general hobby saw for various uses a year or so ago. Ultimately it has sat unused as the quality of cuts are extremely poor. Perhaps good for hack cuts (think what you can do with a jigsaw) but not for anything else. FORGET ABOUT ANY PRECISION WITH THIS. And I do not mean for small pieces... really for anything. Wish I had made another decision. Will likely give away to local good will shop.
[A]:
negative
