Sorry don't know much on how to use forums, but I bought a Nutribullet Rx last year and haven't used it yet. My mom and I tried using it yesterday and the day before, but when I took it off to pour the smoothie, it had leaked inside the machine. Twice. Now, the Nutribullet, I've never had a problem with, unless I use TOO much ingredients. But, I didn't use too much for the Rx and it leaked twice. I'm not sure if I got a defective machine. My mom and I want to use it for soup, but not if it's going to leak. Does anyone know why it would be leaking?
