“The product is excellent, but the customer service is practically non-existent: there is no cancellation form on the entire site, although that is exactly what is promised in the FAQ. In addition, the store does not offer the possibility to cancel an order, let alone return it in a conventional way. You have to pack the product at your own expense, send it back, and then ask CO'PS to cover the costs afterwards. Emails are not responded to for almost a month.”
