I was able to do a search and unfortunately the manufacturer does not give any differences in the EAN codes, which makes it impossible for us to separate them. Basically, the products have a manufacturer's warranty, if something should happen within the warranty, you can send in the products and they will be replaced/repaired according to the manufacturer's specifications. If for some reason the wrong version should arrive, we also have a return period during which a product can also be returned. Please note that a surcharge will be applied if the packaging has been opened. Further details on the return policy can be found in the following link: Return policy
