I bought this product from Greendust on 13th sep, I paid Rs 311 (after discount).
I have been using it almost daily for over 3 weeks and its working really superb, I use it to beat cooked dal , make lassi or buttermilk. But it can be used for other uses as well.
The 250 Watts motor is moderately powerful, the rpm is quite high and it helps a lot. The blade is very versatile & well balanced and dome covering the blade prevents splashing of the liquid. The blender itself is quite light and the cord is sufficiently long. There is not much of vibration and it is almost silent.
None – for this price you cant expect interchangeable blades and 3 speed switch, I think there are no negatives for this item
