We do care about the most of you were able to take part in the training in a convenient time and place.


In order to guarantee the maximal use of training sessions, we have implemented the training fee of 50 EUR, paid during the reservation. After the training, this fee is returned to you in the form of discount for the first Grenton products purchase.


What is important, absence on the training does not indicate that the fee (nor the compensation) would be returned to you.
