Well the other day one of my washer jets blocked up. I whipped it out (oh er!) but after scrubbing it and soaking it, it wouldn't unblock. After messing with it for a bit I had managed to destroy it. A quick phonecall to HH later and they gave me a good price for two new jets (which are different). They had to be ordered in but only took two days to arrive. Brilliant service and very friendly.
