[Q]: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.
[A]: negative


[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]: This type of brush is the only kind that easily detangled my hair without pain. It also is much faster to use. The small brush is very convenient for travel. The handle is a bit awkward to hold but still good. The bristles won’t last forever but they aren’t falling off. Would buy again.
[A]:
positive
