Terrible customer service. I have their atomic digital clock, model: 513-13110TN. The mode/set button is not working to allow me to adjust date, time, etc. I have followed their trouble shooting suggestions in their manual (i.e. new batteries, resetting by taking batteries out and pressing a button 20 times and waiting 15 minutes, etc.). I called their customer service number 3 days in a row. I was left on hold for 15 minutes, only for a recording to come on saying for me to leave a message for them to call me back. Of course, no call back. So I then sent an email. Of course, no response. TERRIBLE CUSTOMER SERVICE. Actually, NO customer service. BEWARE!!!!
