I spent Rs.2700 to buy usha colt mixer grinder 500w with three jars and found out to be not that powerful for tough jobs.This mixer shutoff frequently while grinding thick pastes such as dosa or coconut pastes as it cannot handle such high loads.All other regular jobs like simple grinding, juice making, etc is done with ease.Noise level is decent.Build quality fine.There is no leak or washer issues whatsoever till date.
