Quick defective and dangerous

I had the heater mounted on the wall, now is our young and because the radiator was used. Once switched to wind, then off again. A short time later, when the power was off the Heizelemet has burst and small pieces of glass which were terribly sharp distributed over the changing table. I stood next to it, have gotten nothing, and our little was thankfully no longer on the table.
My conclusion: Not recommended (one star I had to forgive)
