Before use, please read the manual and instructions first. It’s so easy to mess something up if you don’t read the instructions. I washed every piece before use and had to look at the Manual on how to put the pieces back. Once I had that figured out I went to work. I grabbed celery, carrots and apples to juice. It juices at a slower pace than other machines I’ve owned but I actually felt like the juicer was juicing more with this ninja never clog. I picked the amount of pulp I wanted to go through and it was just the right amount. It didn’t clog but did leave behind some residue of the fruit/veggies. The juice tasted freshly pressed and delicious! If you want to be healthy and want to start juicing this is a good machine to have. I love that the carafe is a large size and can hold a good amount of juice. Very easy to clean up and put away.
