Power: 500W vs 750W
This is the most important difference between these two models. The Butterfly Smart at 750W has 50% more motor power than the Bajaj Rex at 500W. That gap translates directly to what you can grind and how quickly.
The Bajaj Rex 500W handles light grinding tasks comfortably: small spice quantities, chutneys, soft ingredients, and small batches of masala. Where it struggles is with harder ingredients like dried whole spices, coconut in larger quantities, or extended idli-dosa batter grinding. Under heavy load, 500W motors heat up quickly and need frequent breaks.
The Butterfly Smart 750W handles the same light tasks with room to spare and also manages coconut chutney, small batches of batter, and harder spices without straining. For a family cooking full meals daily, 750W is the practical minimum.
Jars and Capacity
The Bajaj Rex comes with 3 stainless steel jars sized at 1.2L, 0.8L, and 0.3L. These are smaller than standard Indian kitchen mixer jars. The 1.2L jar is manageable for 1-2 servings. For a family of 3-4, you end up grinding multiple batches for the same task, which is inconvenient when time is short in the morning.
The Butterfly Smart ships with 4 jars: 1.5L, 1L, 0.5L stainless steel jars, plus a juicer jar. The larger jar sizes are the standard for Indian family cooking. The 1.5L jar handles a full batch of sambar masala or chutney for a family meal without needing a second round.
Daily Performance
For a single person, PG resident, hostel kitchen, or someone who cooks 1-2 servings at most, the Bajaj Rex 500W is genuinely sufficient. Grinding a small batch of chutney, blending a smoothie, or making a small portion of masala , these tasks fall well within what a 500W motor can handle. The smaller jars are actually an advantage here: less cleaning, less waste.
For a family of 3-4 cooking full South or North Indian meals daily, the Butterfly Smart 750W is the right tool. Morning idli-dosa, lunch sambhar-rasam masala, and evening chutney , all require a mixer that handles 3-4 grinding sessions a day without overheating. The 750W motor and standard jar sizes make the Butterfly the default choice for family kitchens.
Warranty and Build
Both the Bajaj Rex and Butterfly Smart offer a 2-year warranty. Bajaj is a well-established national brand with wide service availability. Butterfly is a popular South Indian appliance brand known for affordability and reliable build quality, especially popular in Tamil Nadu, Andhra Pradesh, and Karnataka. Both brands have reasonable service networks, though Bajaj is more accessible in North India.
Price and Value
The Bajaj Rex 500W at Rs. 1,799 is one of the cheapest functional mixers available from a trusted brand. For someone who only needs occasional light grinding, this is excellent value. The Butterfly Smart 750W at Rs. 2,799 costs Rs. 1,000 more and delivers significantly more capability. For families using a mixer daily, that Rs. 1,000 is clearly worth spending. Buying the Bajaj Rex for a family kitchen and hitting its limits quickly is a false economy.

Frequently Asked Questions
Can the Bajaj Rex 500W make idli-dosa batter?
The Bajaj Rex 500W can make small batches of idli-dosa batter for 1-2 people, but the 1.2L jar limits the quantity per batch. For standard family-size batter quantities (2+ cups of rice), the 500W motor needs multiple short grinding cycles with cooling breaks. If batter-making is a daily task, the Butterfly Smart 750W handles it far better.
Is the Butterfly Smart 750W good for grinding coconut?
Yes. The Butterfly Smart 750W handles fresh coconut grinding comfortably in the wet jar. Add a small amount of water to help the grinding process. For large quantities of coconut (half a coconut or more), grind in 2-3 short cycles with brief pauses rather than one long continuous run.
Is 500W enough for grinding spices?
For soft spices like coriander leaves, green chillies, ginger-garlic paste, and fresh masala, the Bajaj Rex 500W handles them without issue. For harder dried whole spices like cloves, cardamom, or pepper in larger quantities, 500W may struggle and overheat. Grind dry spices in very small batches to stay within the motor’s capacity.
Does the Butterfly Smart include a warranty card?
Yes. The Butterfly Smart 750W includes a warranty card in the box. Register the product on Butterfly’s website or through customer support after purchase to activate the 2-year warranty. Keep the original invoice from Amazon as proof of purchase for any service claim.
Which is better for a college student or a bachelor?
The Bajaj Rex 500W is the better choice for a college student or a bachelor. The lower price, compact size, and smaller jars are all practical advantages when cooking for one. The lighter build is also easier to carry during a move. If you cook full Indian meals for two or more people, invest in the Butterfly Smart 750W instead.
