[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]: Seller advertised this computer as coming with Windows 10 Pro, one of the main reasons I purchased. The product instead has only Windows 10 Home. An honest seller would provide a free update.
[EX A]: negative

[EX Q]: I bought this product just over a month ago and after washing one of the mugs yesterday I have now found a large amount of dirty water in between the glass walls. I have no idea how it got in there and there seems to be no way to get it out.
[EX A]:
negative
