All of our electronic products carry a 2‐year warranty. For all products under warranty, the first step is to write an e-mail to

We guarantee these products against production defects for a period of 24 months starting from the date of purchase. If you need to repair or replace your product which is under warranty, please be certain to include a copy of the purchase bill and/or of the relevant account. Without the purchase bill or the relevant account information, the warranty will not be considered in force.

The warranty is not applicable to any damage to sender or receiver caused by knocks, drops, or faulty use of the product. This means that damage such as broken antennas or electrodes/contact points is not included in the warranty coverage.

In the event that you decide to open the device and attempt to repair the defect, the warranty will be canceled. In the event that the product becomes defective while still under warranty, we reserve the right to either replace or repair it. No warranty is given on batteries.
