This product is very difficult to use. You have to push extremely hard, straight down and turn it and even then it may not turn on. Then it gets stuck and you can't twist it off. You have to twist the blade on extremely tight and then you can't get it untwisted. Even if you twist on tight it is likely to leak and spray everywhere or into the machine which you then have to clean up. This machine adds extra time to my morning routine. I wanted it because I wanted to have the power to chop nuts. I would not buy this machine again and it wasn't worth the money.
The machine does what it is suppose to, but I continue to have operator error. I am unable to tighten the lid enough to keep it from leaking. I have small hands, with minor arthritis in my thumbs and even with knowing the problem still can't get the lid tight enough. My husband has no trouble securing the lid. I am very disappointed that I am unable to use the nutribullet.
I've had nutribullets for a few years now and when I take the time to drink 1-2 shakes a day as well as regular exercise, my belly fat goes down at a noticeable rate. I always recommend this product to everyone that asks what I do to stay in shape. Diet is the most important part! Eventually your cravings go away and junk food has no place in your life except as the cheat meal and as a reward for beating yourself up after a workout or obstacle course race.
I bought this several months ago and have used it frequently. It does a fantastic job of blending down all sorts of vegetables and fruit in seconds. The only downside is the rubber ring, one has snapped already. I can't seem to find replacements only replacing the whole blade contraption. Not great for the environment.
