Hi everyone. I bought this Borosil Home star 500W Mixer grinder in the nearby shop on a discount offer. Initially it worked very good but later on it began to create heavy sound. Then I took it for service. After the service the sound stopped but the grinding machine got repair. After many services it runs good. It’s durability is too good. I’m using it still now. But it costs more everytime we took it for service. It is better to buy another mixer grinder than spending for its services.
