Kwikot geyser short lifespan

I had an insurance claim where my geyser was replaced by kwikot. I've now had kwikot replace that geyser twice and the latest one is leaking a year after installation as did the previous one. If you're happy to have a kwikot geyser last a year buy one. However I will never touch them again their products are substandard and fail within 12 months of installation.
