I spent almost two months giving food to my baby and I had not realized that black substance was getting into the food until one day instead of food I put water and the water came out black and with black residue.  It was already difficult for the baby to make pupu and he did not explain why and when I realized that I was giving him food that burned at that moment I stopped giving him food made in the baby bullet and since then my baby thank God he returned  to be your needs without problem.  I am really disappointed I bought it with great enthusiasm because in fact I have the nutribullet and it works very well for me, I thought it would be the same with the baby bullet
