Query: Teeth broken on blade drive

Consumer reports raves about it, I guess they didn't use it very long. My wife showed me that two of the plastic teeth fell off, but they looked to be weaker teeth and stronger teeth, so I thought the three stronger teeth would last a while, I was wrong. They were all off in no time. I have had similar problems with other mid-range priced blenders. I am going for the Vita-mix, more money, $350, but at the rate I have been going through blenders, it will pay for itself in no time.
