I made contact on line first, but then was trying to call to talk with someone for more detail. Didnt leave a message the first time, but then called back to do so. Before I completed the call back I was being called by ***. He was very helpful. After receiving the candles I didnt try them right away because it is summertime, but then decided I should check whether all three worked. They did at first but soon after one of the 3.5s (LUM35IV) stopped working. All batteries were newly purchases. Trying a different pair of the new batteries did not make a difference. Today I am returning that candle and hopefully a new one will be sent to me. After that I can confirm whether the Excellent rating I gave was right:-) Thank you.
