We have been Vitamixers for 15 years. My parents were are Vitamixers, my grandparents are Vitamixers and all my siblings are Vitamixers too. It seems to be one of those things that run in families like Ford or Chevy. Anyway, we have ALWAYS used Vitamix blenders and they've been great, but our old one needed a new blade (I had already replaced it once) and even though the motor was still good, I wanted to see how far blending technology has come since we bought our Vitamix 15 years ago. I have heard great things about the Nutribullet, but was put off by the small size of the canister and the lack of different types of lids and pitcher spouts etc. Then I found the Nutribullet Rx which offers a canister size close to that of our Vitamix and I was sold! I asked for it for Christmas. I/we have used it at LEAST 3 times a day since Christmas and I'm a huge fan! I drink two smoothies per day, my husband likes to make milk shakes with it and my son who is autistic and has a very limited selection of foods he will eat gets a smoothie for dinner every evening. It's the only way we are able to sneak protein and fruits and veggies and probiotics and everything he needs into his diet. He is VERY picky! If there is even the slightest chunk of something or his smoothie isn't perfectly blended, he will refuse the entire thing. So far this has been an absolute winner for our needs!I thought my old Vitamix had been doing a good job blending my greens but it wasn't until I tried this one that I realized it had been leaving bits that the nutribullet blends COMPLETELY buttery smooth! Frozen fruits that caused our vitamix problems (banana, avocado, strawberries and peaches) are usually no sweat for the nutribullet. It's faster, easier to clean and takes up less space on our counter. I LOVE it! I only have a few complaints:* It really irritates me that they didn't put liquid measurements on the pitchers/cansiters. That's such an simple things that you just take for granted that blender companies do! Alas, these pitchers don't have measurements so I had to write them on with a sharpie for convenience and easy of use. It's really, REALLY dumb that they didn't do that.* We have found that if you allow it to run its cycle and shut off automatically, the resulting beverage is too warm. If you're making soup or bulletproof coffee then no problem, but for smoothies, bad news. These blades spin fast and blend fast and in our experience, the smoothie is ALWAYS done MUCH sooner than the auto shut off, so we just push the button to stop it manually or pull the canister off the base which also stops it. Even then, we have to be careful not to let it go too long or add extra ice cubes to compensate because we find that this heats up the contents WAY faster than our vitamix use to. Just something to be aware of.*While we find this way easier to clean than our old vitamix, this blade assembly isn't allowed in the dishwasher. Sure it's not hard to wash by hand, but I always have to deduct "points" for kitchen gadgets that have parts that are not dishwasher safe. At least if you're going to make a part that can't go in the dishwasher, include a special brush or something for cleaning it by hand, or some sort of stand to put it on while it dries or isn't in use. We end up letting it dry in the sink and keep it on its side on the blender itself (see pics).*The only other thing I miss about the vitamix is the ability to choose my speed and power level. This thing does not have that ability. That keeps it simple which is nice, but I just want to mix instead of blend or extract nutrients and full power/speed is way overkill. It would be nice if it at least had an option for low and high speeds.All of that being said, when you compare the price of the vitamix and the nutribullet Rx with the performance and features, what you get for your money in the nutribullet Rx is FAR SUPERIOR in value to what you get from a vitamix or probably a blendtec for that matter (though I can't speak from personal experience). Before you spend hundreds on one of those blenders that has a lawn mower engine, I highly recommend you try the nutribullet Rx first. It gets very heavily used every day and has yet to find a fruit, vegetable or powder that it can't COMPLETELY emulsify.I sincerely hope this review has been helpful to someone else! And yes, I paid full price for this. Feel free to ask any questions!
