I got this a Christmas gift (although I picked it out and set up the purchase), and I couldn’t be happier. We had a Ninja before, which worked well and suited out needs, but the vitamix is just that much more powerful! 
The tamper is a great feature for making thinks that are not a liquidy (ex: hummas, or black bean spread)! 
I haven’t tried everything I want to yet, but I have full faith in this machine. I am looking forward to making baby food, and peanut butter, and lactose free ice creams. 
It’s a great addition to my kitchen. 

The only con I have, is that the jug is wider and shorter than the others. I thought that would be a good idea for counter space, however I think the taller slimmer hub would work better, as sometimes ingredients stick to the sides rather than going down to the blades. But over all, it’s a great product.
