I have RA, with this illness is very difficult to open back and forth the open upside down jar, it is hard and spills the juice very often. Unfortunately the model that has a regular jar is extremely expensive.
I was hesitant to purchase such an expensive item. However based on prior reviews I gave it a shot. I have never regretted. I make green smoothies in the am for breakfast and lunch.It is so convenient and there isnt a gasket on the blade to scrub. I just use a little soap and its clean. I love it. I thought the size was over kill at first. It is perfect.
I find if I don't turn the blades 1/4 turn more than I think I should that it will leak out into the base, when the cup is on the base. I am not over filling the cup. Other than that its great.
