distributes its products in over 85 countries. 
All our products fulfil strict quality requirements and legal stipulations in the EU. In order to ensure the quality, 
our products regularly go through an extra quality check, both by an internal quality department and by 
specialized external organisations. If, all precautionary measures notwithstanding, problems should occur, 
please make appeal to our warranty (see guarantee conditions).

occurred in the first year after the date of purchase and delivery, or a replacing article at 50% of the purchase 
price or a refund at the value of 50% of the retail value in case of a flaw occurred in the second year after the
