We had almost the same product like this in our house.
Bajaj is really Good Company and a very trusted one. The best thing about Bajaj Company is their product is always the best.
My parents bought this type of Grinder 2 years back. Till now it is still working fine. We have been using this product almost everyday and still didnt face any problems like over heating or loose blade or whatever. We have another Mixer but Chinese brand and the funniest thing is it last for 1 month only and this Bajaj one last for 2 years and still working fine.
Thanks to Bajaj for giving the best products.
Almost all our electrical gadget are Bajaj Brands now Because Bajaj is a very Trusted Brand
