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!

positive

I have a smallish black dog that disappears into shadows and night an this collar is perfect to help keep an eye on him. He is so small I was able to get two equal lengths out of the collar portion and I love that it is rechargeable.
