Had a Mira electric shower repaired under warranty - the engineer says the new part (heater tank) is only guaranteed for the remainder of the original warraty period - i.e. one month! Started to complain that this was unaccep table but he said 'take it up with Mira, nothing to do with me' as he walke d back to his Mira-logo emblazoned van.
Since there's practically bugger all else in the shower *apart* from the he ater tank, I think Mira are taking the piss. The previous shower (same mode l) failed for the same reason when just under six years old so this repair better last a damned sight longer.
