this heater has no unpleasant odor like conventional rubber hot water bottles. His warmth is nice provided of course good to his little bag fleece otherwise burns on risk. Some minor drawbacks: -at the end of the 3 mins charge, my model (sole mio 71) does not stop automatically. -The zipper of the bag is too small and you should scrape the heater for bringing hence risk of scratches. -to like some screwdrivers, it was necessary that I first load 5 to 6 times my machine to quickly provide a strong and sustainable heat. -and finally, small detail that is signaled in the user guide, if the charge takes just 3 mins, heat, as to him shall not be optimal only after 15 to 20 minutes. Warning, if you use it to warm the bed in advance, consider moving the unit so that there is not one too hot. But for the chilly, it is also possible to keep on the lap to warm hands or can put it down to set foot there.
