My wife bought this BL1300 blender about a month ago.  It was mostly used by my mother-in-law to make fruit smoothies.  It worked fine the first few times, but then it started vibrating a lot when using it.  I was about to tell her to stop using it since it sounded so bad, when it stopped working by itself.  It would just click when trying to turn it on.  I picked up the base and realized the motor was completely loose. I tipped it around a little and 4 screws fell out of it.
