Was concerned when I got the E1 message that many lower star reviews mentioned. You have to make sure that the blender cup is fully locked in and the white cover is secured and locked in place so it makes contact with the seal on the side. This makes the message go away.

I absolutely love this. Makes making my babies food way easier. It's all done in the same product so I don't end up with many dishes at the end. I would say the only thing I didn't like is that the plastic stains very easily on the first time I used it the carrot stained it. But either then that it works great wish I had it with my 1st child! But now I can make foods for my 3 kids.
