I'll preface this by saying I own about 9 different Breville products but their Kettles are the absolute worst. After going through 2 IQ kettles, which lasted about a year and a half each, conveniently past their warranty period, I switched to the Crystal Clear. I thought everything was going well since the water boils normally. I regularly go through a vinegar cycle with these and baby this to the point where it still looks like a like new product. However, behold, the lid stops working. Just when the water starts to boil, the lid will pop open, and it will continue to boil indefinitely until you turn it off manually, or force close the extremely hot lid. To add to this, this is already a warranty replacement unit. I guess their products just aren't made to last over a year and a half to 2 years. Extremely frustrating.
