I purchased mine after Christmas and use it almost every day. My only problem with it is after everything is mixed and trying to open it. I understand it creates a suction when using, but I have a hard time opening it. I eventually get it open but it is hard. If I do t get it on tight it spills out.
I decided to do a 20day cleanse and bought this so that I could quickly make smoothies and go! The NutriBullet PRO is perfect for this. Once I adjusted to using something new, no problems at all.
I brought one 2 years ago and it stopped working. The tabs get stuck. if you are not able to fix the tabs the service team would try to sell a new one to you. YouTube the issue
