Buy this infusion has to repeated times. For me it's a great infusion because he - Very long and intense smells, even when only the bucket is prepared in the sauna while warming up. - Is not intrusive, breathing does not fall a heavy, on the contrary. - Does not sting the eyes (but I wear contact lenses, can not judge without !!) They come from so long. I also have the spring cleaning times a already open bottle again found the more than 1 year was open, and he was still as good as new! So something for people who use it rarely, because it does not spoil. Price is also ok! Just buy it from me.
