"Rubbish, Rubbish, Rubbish. Mine broke three times in two years. Biggest problem is red ring that is built in to the end of the cartridge, and then clips in to the temp hub assembly, is very weak, and breaks constantly. You cannot get a new one, you will need to buy a whole new cartridge assembly (£70-80) just for one plastic ring. Also the cartridge in mine went within two years, so that needed replaceing aswell."
