Feedback from Ambrosini Stefan on the 04.06.2018 also the Ultratrail walked 84 km in Schwarzach:

Hi Gerald! Super your Mozart ointment. Have applied to the foot. Swelling and aching leg muscles are almost gone! That must be a magic ointment, thank you very muchI would like to order 5 ointment with you!

@ Ambrosini Stefan: very pleased that my ointment has helped you so quickly at your swollen feet! Good luck with the 100 KM Marathon this weekend in Biel.
