Query: What a piece of junk!

I am EXTREMELY disappointed with this model! But to be truthful, I haven't even had the chance to use it yet. Over the last 2 days I have had to buy 2 of them from Target (which I shouldn't have had to do since only the battery needed replacing, but doing that costs as much as a new model). In the first one, the black housing was separated, and I had to click it back together. There was also a large crack on the brush tool as well as a large chip on the dust bowl. I returned that one, thinking it must have been a fluke. With the second one, the unit would not sit in the charger properly so that the charging light would come on -- I had to wiggle it back and forth to get the light to come on, but it wouldn't stay lit. This is TERRIBLE quality control! These units are, of course, made in China, and we are getting TERRIBLE products from China! I have wasted three days of my time and $47.00 on this.
