I bought the Nutribullet 900 about 5 months ago and used it so much that I wanted to go for the Nutribullet RX. I LOVE BOTH OF THESE! I use the Nutribullet 900 to make frozen smoothies and the RX to make soup. I just throw in fresh vegetables and greens to make the soup and frozen fruits and vegetables to make the smoothies. If someone tells me they are feeling tired, sick or want to lose weight, I tell them to get one of these and start extracting fresh organic foods and get off of the processed foods. It is important to make sure the bottom of the RX is securely in place, because when making soup and the unit vibrating for 7 minutes, the bottom can become loose and leak. They give you a tool to make sure it is tight and it also helps in getting the bottom off when you want to clean it.
We bought two NutriBullet pros. Both units have had to have the base units replaced and need it again. This appliance is a great idea but very difficult to clean and not durable. We plan to replace ours with a more durable brand. (Consumer Reports suggested to NutriBullet owners that they discontinue using this brand.)
I first bought the product for my mom, but after my niece was diagnosed with high blood pressure I decided to get one. She has since lowered her blood pressure and lost weight as have I. Three months after feeling great, I order one for my sister.
