I went crazy looking for one of those. I have a swedish one (very cute, makes four heart-shaped waffles) but couldn;t find another for the life of me. I finally found this weird one, that needed to be put on an open fire outside to burn the wax or whatever it was treated with off (!!!!) (not very easy for her, living in an apartment in london! In the end she had to lug it on the bus across town to her friend's house who was having a barbecue).
Anyway, once i had that i never saw the point of having another electric appliance to take up half a cabinet space. It works perfectly, you heat one side, then put the batter in and turn it over. The other side heats and cooks the other side, and then when you take that one out, you pour the batter in the second side it was on, that is, take one out and pour the batter in.
