Is it just me or does anyone else find the Truma control panel knob extremely irritating in its inability to offer any tactile feedback when pushed? I'm starting to wonder if ours is faulty as we sometimes get no acknowledgement of a setting from the control panel symbols when pushed and because there is no reassuring 'click' like a 'proper' button We end up pushing it again but harder; not too dissimilar to talking slowly and loudly in English when abroad in the deluded belief that you will be understood! Starting to wonder if we should invest in the Truma iNet box just so we can set it via our mobile (which ironically does not have 'proper' buttons!)
