Bought together with the warmer of the Romans roaster. Works great, unfortunately, am so far never got there with the specified 90 min. The apple was still very strong. 2 hours should be there already. In addition, it is advisable to Apfen between times to turn, so it does not melt fastened. Should go Wenns times faster, so just fit also 2 tea lights in the warmer here but you have to take good care of the apple, otherwise it tastes like burnt. The glaze on the inside makes it easier to clean and is very hygienic. The handle on the lid looks a bit clumsy, but you get no hot fingers. The size is sufficient to accommodate even larger apples - in comparison with other products from other manufacturers (eg worldview, here fits with a small fortune halved apple in) - A great invention.
