Because we are a web shop, we focus primarily on online support. And because we want to maintain low prices, there are certain things we cannot do unfortunately. One of them is to be constantly available on the telephone. On our web shop, we try to provide as comprehensive as possible any information you might need. We also have, most of the time, a direct link in the product description to the manufacturer's website, where you will find all the information about the product. Nevertheless, are you still having questions? Then you can always email us! Usually we respond very fast on emails, considering we are focusing mainly on online support. Do you still want to call us? The phone can only be answered if the activities and work permits us. If it is not possible, then you will get to hear from our answering machine to request you to send us an email.
