Review on Replacement Cross Bullet Blender Juicer by George Woods

I was looking for a replacement can (it broke) and an extra blade for my nuwave twister. Someone commented on the question that these parts are interchangeable for nuwave twister and magic bullet. They are the right size and fit the twister. HOWEVER, every time I tried to blend it, the screw holding the blade to the lid would come out and the blades would come loose. This screw must either be reverse-threaded or have permanent "glue" present. so he doesn't fly away. Otherwise it doesn't work. So as a replacement, the glass will work, but the blade/cap will not.
