bought an expensive Clarke High Frequency Automatic Battery Charger back in 2015. It failed within 12 months, after very light occasional use. The Store wouldn't replace - said they would need to send to an engineer. So weeks later I get a call saying it was broken (yes I knew that) and they would replace it. Great but another 40 mile round trip and more time wasted. And guess what the replacement just went wrong after occasional and light use. No chance now for a replacement or refund as its over 12 months since the last debacle. I may as well have bought a cheap one from ebay!
