We brought our low wattage travel iron which us on the 3/23 Magic sailing. Used it about four times with absolutely no problems, and loved the fact we didn't waste precious vacation time waiting in line for a beaten up old iron in the laundry room.
Regarding those claiming our type of iron "put them and the ship at risk," I politely suggest they (a) look up the term "circuit breaker" in the dictionary and (b) lwould love to hear them explain how the our type of iron puts them at more of a risk than all the burning cigarettes I saw on board (which Disney continues to -- ugh -- allow for heaven knows what reason).
