This evening, we received a letter regarding the same candle.
To whom it may concern,
We purchased this candle before Rosh Hashana at one of the local Lakewood supermarkets. It seems to be a new product, so I figured that I would spread our experience with the tzibbur to prevent any tragedy in the near future.
On the second day of Rosh Hashana towards Mincha time, my wife smelled fire coming from the dining room where our leichter tray rests. We checked out what it was and we noticed the plastic of this candle completely melted all over the tray with a small fire circulating around the leichter from the plastic and leftover wax. We quickly moved the tray into a sink where we knew that we can keep the fire contained.
Baruch HaShem, after a few minutes and circulating the rest of the tray with water to prevent the fire from growing, the fire extinguished itself. The only small damage was to our leichter tray. Obviously, the results could have been way more devastating, especially on a day like Yom Kippur when everyone is in shul.
