I brought this item about a month ago this has been the best nutribulletpro I ever brought better then the 600 watt is more powerful the 900 watts my drink are done more quicker then before and the cups are larger. Great improvement ...great machine love it....
the only problem i have had is,The base is hard to unscrew due to the fact "which i found out the messy way" that one has to tighten it quite a lot otherwise the vibration will loosen and it leaks.
