We bought this hand warmer because we wanted well prepared to survive the coming cold days, but honestly: This thing is out of place. The design is very attractive and looks (!) Quality from. These hand warmers that you get at Aldi, Lidl and Co with this fluid are much warmer and keep the heat even more as this electronic hand warmer. These were perhaps just felt 25 ° C, and no 40 ° C as described. Conclusion: it would not buy us, are much better alternative.
