Kit Construction Support

If you have problems whilst constructing any of our products we do provide a free diagnosis service. Firstly, we will attempt to solve any issues via our support email, and will request from you:

  1. Confirmation of steps followed in the manual’s assembly guide and troubleshooting section.
  2. A high-resolution, well illuminated and focused photo of the product (including all soldering points and tracks).

If we subsequently find a faulty component has been issued, we will provide a free replacement or refund, plus refund the cost of any postage to the buyer.
