This review is on behalf of my dad, he has a log burning stove and although it gave off a lot of heat it wasnt circulated around the room, this little fan turned up well packaged and in no time at all. To look at it you think well how will you work? there is no batteries,leads or wires,but when placed on top of your hot stove it comes to life!! and boy does it work! the warm air circulates that well it keeps the whole of the downstairs floor warm,, so no need for the central heating to go. Its a small fan, light and a nice simple design even when its not doing its job it sits there looking smart. Anybody with a logburning stove should think about getting one of these its worth its weight in gold!!
