You can add products to the watchlist and compare them with one another or send us an inquiry. There are watchlist symbols on product pages and product tables for this purpose.


For registration, an order number with corresponding serial number of a device and the bold marked entries are required. This serves to verify the entry and authenticity of the data. Registering a user also registers a product if it has not already been registered. Here also several orders and/or products can be added at the same time. Depending on the number of products, this may take some time. If multiple users of a company need to be registered, already registered products can be used for this authenticity check.
