Query: Won't last if used regularly

I received this as a gift great timing as I needed a new blender. I use a blender about 2-3 times a week we love smoothies incl. my kids so when we use it is not just a single serving. Well the bottom seal wore out within a couple of months, its difficult to screw on if you don't just get it exactly right. The spout falls apart which then causes more leaking, also the auto serve is useless for most cups because of its positioning. Overall one of the worst Back to Basics I have ever had.
