Taką odpowiedź dostałem kiedy zapytałem o gwarancję:
All products come with our 12 months seller warranty and you can have them returned back to our London office for service in case there is a problem.
However these guarantees are not official and they are being performed by our in house repair agent.
You may find more information about our guarantees below:
