This was a very bad product from kenStar company.I am useing this KenStar Senator MG 0120 mixtur grinder from one year it was not working good , it stops very quickly without any over load and it was working with bad sound when we are useing .And the bleades of the jars are not moving smoothly they are fixing very badly and the carbon brushers are damaging very quickly and the motor also heating very quickly.It is wast of money , so friends please do not buy this mixer .It is better to buy another company mixer.
