This is an article that fulfills its function: to allow Madame enter a tepid bed, even when winter temperatures make the frankly cold atmosphere. The principle is to let it remain under the mattress topper bottom sheet and plug it into a power outlet. The system then we can at will turn to warm the bed and adjust the temperature by choosing between three positions (in practice it is often put to the maximum setting but it takes something for everyone). It should ideally consider plugging a good ten minutes before going to bed as this remains a heated blanket and not a cooking plate: it is only 60W and the effect is not instantaneous. Once the preheated bed, it is advantageous when the device cut back under the duvet for the warmth of your own body will be sufficient to maintain the small warm cocoon created; otherwise the risk of falling asleep forgetting is not negligible. For my part I prefer to avoid this to happen because it is useless, it will consume a little electricity (60W good it's not Peru but still) and finally the idea of having a magnetic radiation - even low intensity - in a human body for hours not delights me. The dimensions are perfect for one person (no need to cover the area of the head where the pillow is). Everything is washable and seems well made, so it's perfect.
An investment that cautious and timid will not regret!
