"Pro" is that this is a WONDERFUL unit and almost exactly what I was looking for to dry up my damp and sometimes even wet basement, even when it's put in a less than optimum position in my basement. The "Cons" are: #1 that the drawback from this unit working at it's best would be if I could put it in the very center on my basement. But the short length of drainage tubing that they send with it won't allow getting from the unit set in the basement center to my sump pit. So I started looking for the same kind of tubing to purchase a longer length myself. YES, I CAN rather easily find the same diameter tubing, but I CAN'T find it in the nice soft and very pliable consistency that lays nice and flat on the floor. I called the company and the person gave me a recommendation of a kind of vinyl tubing at Lowe's of the same diameter. But it was much more stiff not anywhere near as soft flexible as the kind that comes with the unit. It came in a coil, was unmanageable, and kept curling up into ringlets. I'm sure that there are other people who buy this unit who would like to have a few more feet of discharge tubing, but the company, so far, refuses to tell us where we can purchase more tubing and exactly WHAT "kind" it is. In fact, if they were smart, they would sell some of this soft pliable tubing themselves to those of us who want it. The 2nd "Con" is that I would caution anyone (like MANY seniors I know including myself) who still has a landline and doesn't have a "Smart Phone". If so you will be unable to register for the warranty for your appliance, because they won't accept warranty applications for anyone who has a landline #. I know it sounds crazy, when you, like me have a lifelong AAA credit rating with companies like Chase, have done business with Amazon, Ebay and many others for decades and no problems, but this company won't give you a warranty for their MOST expensive dehumidifier (that you've already paid for) because you have a landline #. WHAT kind of a business does that?
