I used this product for 4 months and within this period it was almost dead. Basically mixing of some liquids the thing to be mixed pours out of the mixer vpuls and accumulates at the bottom edges, thus damaging the internal circuitry. The blades gets frequently jammed and stuck during operation. The boul caps should be more hard to hold the mixing part inside it during operation. Also the mixer is quite heavy though small. Prestige should make improvements in all these to make it more effective
