Just in case
The repair price is normally around 60% of the original price. We will immediately inform you if a repair is not cost-effective.

You will not be charged if your parts are scrapped on our premises. A flat rate of €50 will be charged for time and materials if we return components that have not been repaired.

You can find the prices for Power-Check calibrations here

Repair process:

  1. Carefully pack the defective components into a box.
  2. Enclose a delivery order with contact information (phone number or email address) and a description of the problem.
