Not the op but I don't think it blends better than others. What I really don't like is the little split in the removable blade where food sticks into and you can only remove using a dental floss or a folded piece of paper. Knowing that I would have got one with a fixed blade.
I just throw the blade in the dishwasher and it has come out clean every time.
You're right that it isn't as fast as some other blenders, but I think it makes up for it with the simple and durable design. I can live with having to run it for a bit longer.
