[Q]: Very easy company to deal with. I own a cleaning business and my employees love these mops. They pick up great and can reach under just about everything. A little pricey but worth it!
[A]: positive

[Q]: Definitely not worth the money. They overheat and burn my ears very quickly after being turned on, the battery life isn't more than 30 minutes, when trying to watch a show or video the audio is very behind and they have this constant beeping/buzzing noise while they're on that you can still hear over your music.
[A]: negative

[Q]: The brackets that hold the bar arrived with a few small dings on the flat surface, and a tiny flaw in the finish. Tiny, but I wanted them to look perfect. Everything else arrived looking great (my hose is metal). I called Delta and they are sending me new brackets.
[A]:
positive
