The period commences upon receipt of this legal information in written form, but not before the recipient has received the item(s) (in case of recurring delivery of the same type of items, not before receipt of the first partial delivery) and also not before the fulfillment of our information obligations according to Article 246 2 in connection with 1 para. 1 and 2 EGBGB (Introductory Law of the German Civil Code). Timely despatch of the revocation or the item(s) shall be deemed sufficient for compliance with the revocation terms.

    Effects of revocation

    In case of a valid revocation, any services or products received by either side are to be returned and any accrued financial advantage (such as interest) shall be turned over to the other party.

    Should the Customer not be able to reimburse services or products received (the amenity and advantage of using) wholly, partially or only in a deteriorated state, the Customer shall pay compensation for any loss of value. This does not apply if the deterioration of the merchandise is related solely to the inspection and verification of the product's properties and functioning in the same way the inspection would have been possible and common practice in a store. In the case of usage exceeding an inspection ECS reserve the right of charging the Customer any decrease in value caused by that usage.

    Products which can be mailed as a package are to be sent at the Customer's own risk. The Customer shall bear the cost of return shipment if the delivered merchandise complies with the merchandise ordered and the price of the returned merchandise does not exceed 40 Euros, or if at the time of revocation the price of the merchandise is higher and the Customer has not yet provided the consideration or any contractually agreed installments. Otherwise the return shipment is free of charge for the Customer. Merchandise that cannot be sent as a package will be picked up at the Customer's residence. Obligations to refund payments must be met within 30 days. The respective period of time begins for the Customer with the sending of the notice of revocation or the merchandise itself, for ECS it begins with the receipt of the revocation or the returned merchandise.
