This jewel lasted a little over 100 days (guarantee runs for 90 days) and then it went geflunken! I called their product customer support to see what could be done and evidently I interrupted them on break and the support I got from them was Zero, Zip, Zilch, Nada!There are several 'Renewal' dealers on Amazon; I suggest dealing direct with Amazon instead for better service and satisfaction even if it is somewhat more expensive. Otherwise be prepared to bite the bullet when you deal with Second-Handers.
