Best blender mixers in India for smoothies and spices?

Hi guys, I want to buy a blender mixer for my mom. Because of dental surgery, she will be on semi- liquid diet for 2 weeks and will have to grind all food. She has a conventional mixer grinder, but I was wondering if these bullet mixers will be better for her as she has to use it for every meal.

If you have used one, please suggest a good brand I can buy. So far I have come across Wonderchef, Prestige, Pigeon, etc. TIA
