[EX 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!
[EX A]: positive

[EX Q]: Although this pump is smaller it works great for the value. I used it on the farm to spray fence rolls and it can reach over 10 feet of stream. We are very please
[EX A]: positive

[EX Q]: I order small size and received extra large! Now I have to pay to return them, and until then they will refund my money. They made the mistake, and I have to fix it? They should send me the right size I order, and apologize for the inconvenience.
[EX A]:
negative
