Product review (1 stars): Quit working on third session. New one would not work either.
Used it two times.  Worked fine.  Third time the low water indicator came on and and it would no longer work.  Tried emptying it three times to no avail  No instructions in book on who to contact.  I contacted Knox direct through their web site.  Told them what I wrote here and got a reply that the will send me a new one.  Surprise!  Now waiting to see if they fulfill that promise.
New one arrived and would NOT work right out of the box.  Ice full and low on water icons came on and it beeped and quit.  No response from Knox after several e-mails.  Guess they don't want to mess with me having two bad machines in a row.  Thought maybe this was a good company as they did send a second machine without hassle.  I'd send it back for research and repair if they would just contact me.  Other wise I have no choice but to toss the two for don't know where to get them repaired.  No warranty info sent with packages.
