Good product range, but they lack in transparency. Any product which is picked up from the store cannot be returned! This is the law, yes, but they never say it transparently.
I ordered online and picked up in the store, but I did not test thoroughly the product at reception. When I discovered a fault and went back after 2 hours, they did NOT WANT to replace it, but SENT it to WARRANTY. Deadline 14days...
