Worst company ever they ship you the wrong items over and over & expect you to pay for wrong equipment. Seriously ridicules ... After ready reviews I thought I'd post mine too. And for those that struggle with egregious idiots at every level of lincare there is government agencies you can file a formal complaint as well as the BBB. If lincare can't clean up there act then it's up to people like me & you to shut them down stain them with fines after fines until we the people have some god damn dignity ....
