Breville BBL550XL 5-Speed Blender

I have a Breville Ikon and it's the worst blender I've ever owned. It's frustrating and aggravating. Whenever you have any frozen ingredients, the bottom of the blender twists loose and the liquid ingredients flow out all over the blender and the counter. Even if you try to retighten the assembly after a short pulse, you often don't catch it soon enough and it makes a big mess. They replaced it once, saying they'd never heard of it happening. The same thing happened with the replacement. Avoid this one if you chop ice or use frozen strawberries or that kind of thing.
