    These boards work well for the purpose. Giving 4/5 as I had one relay stop working within a few weeks.

    • Hendi (store manager)

      Hi Gareth, not sure if you have a multimeter to check if it is the ‘relay itself’. If yes, we would be glad to send you a replacement relay.

  2. JC van der Westhuizen (verified owner)
