Query: leaks, doesn't blend previous KAid Blender much better

I had the previous model and when the teeth broke I bought this one. The only positive is the large size of the plastic container. I make smoothies for my kids for the week and I puree a lot of steamed vegetables.This blender leaks from the bottom.This blender cannot blend anything if it is slightly frozen.This blender is deafening.Extremely disappointed after years with my previous kitchen aid blender.
