Buyers on the internet
It is legal to re-sell authentic Silltech and/or Crystal Cable products that were purchased in their original, unaltered form. However, we find it very unlikely that one of our customers will re-sell their products through the means of wesbites like or similar to eBay or Alibaba. Therefore, we advise to purchase our products only through our licensed distributors’ website and/or store.
In case of any doubt about the authenticity of products offered for sale containing one of our trademarks, we urge you to ask for the serial number corresponding to the offered product. In case the serial code cannot be provided by the seller, our rule is that the product offered for sale is a counterfeit. However, in case a serial number is provided and doubts about the authenticity of the product still exist, we advise you to contact us in order for us to verify the serial number. You can contact us about these matters by filling in the form below. Pictures of the product can also be added.
