Hi friends in my own experience i’m talking about this mixer grinder. I am using this grinder since 1 year. It was running very well since than. Now few days ago it has some problems in the internal regulator. I have repaired it completely and it is running fine. It is a very good mixer grinder. Blades are very strong and sharp. You can easily grind things very easily with help of this grinder. Really impressive performance by this and I have not faced any grinding issue with this.
