I thought that to Super cushion this product I will give a chance, despite the many different reviews from total crap. As always, great shipping, but the content was still really a disappointment. The cover feels totally inferior and prevents strong at heat transfer. From the "heat" also lacks any trace. I have not expected that the cushion is so hot that it could create burns or which one pulls the finger is wenns too hot, but it is no trace. After 30 min Level 3 (MAX) the pillow had a decent heat straight at one point only. Some bodies were even cold. Conclusion: Poor heat distribution and development and poor quality of the cover. Would recommend all the fingers to let them and VII to acquire a similar Kirschkernkissen or. Wärmeflasche tuts also 100x better.
