Geyserwise Max Controller Best Ever Service

I have for years had Geyserwise Max controllers' in my homes. Could not live without them. Up to recently they work 100% and were able to take the strain of the various power outages. my current one developed a small fault where it would not retain in its memory the time and day. Spoke with Gavin van Eck at Geyserwise who immediately addressed my problem and replaced unit. All is well and up and running. What incredible after service, thank you.
