Has anyone used one or seen it?

It is extremely impressive the amount of smoke that is produced but for its price it is a big risk if it does not work perfectly. Voitko produces high quality products but still no smoke device has been proved to be 100% reliable. I suppose that he would not sell it that much if it was not a great product. Best thing to do would be to see it live but if it is not possible at least contact the seller to give you more info personally. Not many magicians will buy it as this product is for the very serious performer that undoubtly wants to incorporate smoke to his act and difficulty you will find someone here to inform you.
