We bought this mixer some time ago, and found it to be a very bad product. First it makes a lot of noise, more than usual and also vibrates so vigorously that everything in the kitchen starts to shake. Also, it takes a lot of time to grind properly, about 2 times the time my old grinder takes. Also the design of the mixer is so poor. Each time I need to open the jar after using, I have to make a lot of effort to open it. Moreover its a hassle to use and clean the mixer.
