I make a shake every day, have for the last 10+ years. I use a multi speed Oster pro1200, that replaced a very old push button Oster. I bought Vitamix 7500, used it a few times and it got put on a shelf in the pantry and forgotten about. I absolutely hate the Vitamix. I don't like the sound it makes, I have yet to get it to not over blend/crush ice and I do not like the plastic vs glass. I am the only one so far here that is not telling you how wonderful a vitamix is, so its obvious I am the odd man out.
I have the same level of disappointment with my Vitamix as my 10 year old daughter had with chocolate chip cookie cereal. I was really thinking that a $400 blender would be life changing, but it did not do anything I wanted
