Bought about a month ago. Still learning about it. I have found that if I don't put enough liquid it for smoothies the motor just whirs. But then I add more liquid and it's fine.
Love how the Blentec crushes ice and frozen fruit and makes everything so smooth. This is an amazing machine. Great for so many food items. The way this machine will grind rice into a fine flower. I also like how it will blend hot soup.
I submitted a claim via online because my jar was creating a smoke and burnt the seal after heavy use for 3 years. I got a new jar fairly quickly.
The only thing is the new clear plastic piece for the lid is much smaller and fell into the garbage disposal and distroyed it on first day. :-(. Thankfully I still have the old one that I kept. Regardless, awesome service!
