haha I'm drinking one right now. Got it for xmas. I use it everyday.
I always ate healthy but this makes it easier. Just chuck healthy shit in it and blend for 30 secs. Taste good as long as you've got enough berries, banana etc. Usually I put in kale, baby spinach, frozen berries, almonds, flax seeds, goji berries, sunflowers seeds etc.....dear god, I sound like an 80 year old.
It's not a juicer though. Small berry seeds don't get chopped up and if you put too much celery, carrot, apple etc it can be quite thick/pulpy.
I think it's worth the money.
Edit: I almost forgot, it's a piece of piss to wash. Takes no time at all.
