Product review (5 stars): Tube was a little stiff and a little too long.  Otherwise, very, very good!
Comment on the product:  The plastic tube was very stiff and somewhat difficult to bend into the required shape at first.  The old tube I was replacing was more flexible.  Unlike other reviewers here, I found the replacement tube to be a little too long!  I had to trim an inch off it so that the humidifier's cover would snap shut.  As it, it's a little effort to close the cover.  The manufacturer's instructional video that the seller provided was of great help!
