Information regarding the right of defective performance is contained in the Terms and Conditions document. On this page you will find more information about warranty and after-sale service.

On receipt, you have to check the condition of the parcel (number of packages, intactness or damage of the packaging, etc.). Likewise, on the day of receipt, check the completeness of the goods and whether the parcel contains what is should. If not, please inform us immediately of this situation.

Warranty period

two years - valid for consumer buyers worldwide
one year
- valid for a business buyer

2 years warranty

The warranty period starts from the dat of receipt of the goods. In the event of a claim being settled by way of exchange or provision of a replacement part, the new time limit does not run, but the original one continues. After the claim has been settled by repair or replacement, the warranty of the goods is extended for the duration of the claim (from the day after the claim is made until the day on which the buyer is informed of the settlement).

For products purchased as kits (kits, accessories, parts), the warranty applies only to each part separately. For assembled products, the warranty also covers the complete device. The warranty does not cover normal wear and tear due to the use of the goods for their intended purpose.

The warranty does not cover damage caused by:

- improper assembly procedures,
- wear and tear caused by normal use of the goods for their intended purpose,
- improper handling or maintenance,
- long-term neglect of maintenance,
- use in unsuitable conditions (in particular climatic conditions, dust, temperature, humidity, etc.),
- natural elements or force majeure,
- mechanical damage,
- electrical surges,
- improper installation, handling or operation,
- modification or intervention by the purchaser (or a person authorised by the purchaser).

Application of warranty

The basis of any warranty claim is two-way communication to ensure that it proceeds smoothly and does not prolong the time required to deal with the situation. Although we prefer direct communication via our email address, you may also contact the online dispute resolution platform set up by the European Commission http://ec.europa.eu/consumers/odr/ with any complaints.

There may be several reasons for returning the goods. To help you find your way around, here are the most common ones. It may be that you don't like the product or it doesn't fit with other picls in your hamshack, you chose a different variant, you wanted the product in a box or with a different connector and you inadvertently ordered another one. Or the item doesn't work the way you want it to, or something is missing from the shipment. Everything has a solution!

What is wrong with the goods?

Before proceeding, prepare everything you will need. This will be the invoice and its number (this document can be found in email), the name of the goods and their serial number (also indicated in the sent invoice and physically on the goods and their packaging).

Another important point is the description of the problem, if we have sent you another product by mistake, explaining it will be easier than if the product is not working or you are struggling with its settings. If you are unable to set up the product or incorporate other devices into your system, we recommend reading the manual for the product, sitting down with and trying again. If none of the above has helped you, we recommend contacting us.

All products are tested, so it would be a shame to send back a working product without communication and wait for a new and identical one to be sent (if the problem is in the wiring, it will unfortunately not be solved by sending a new piece). Simply put, manuals are a good partner, if they don't help you, then drop us a line and we'll sort it out together!

I don't like the goods or they don't suit me

Your package has arrived and you can't wait to unwrap it and enjoy your new toy. We all know it, it can happen that you don't like the item, despite the photos and dimensions you imagined it differently.
