Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Confused

I read all the great reviews and I was sold. This is the lens for the price. I guess it sure is because one day I was trying to shoot with it and it was making funny sounds so I switch from AF to MF and then the glass falls on the carpet and front of me and all I can think is "uh oh." Apparently to repair this puppy it costs about $30 more than buying a new one, that's pretty standard for the throw-away society we live in today.
