Butterfly Cute Wet Grinder with three stones

[Vaidehi Kishkinthan]

Has anyone any experience with Butterfly Cute Wet grinder that comes with three grinding stones? It is currently being advertised for about $ 150. When compared to other conventional wet grinders, this price seems to be very good and with the Butterfly name, this grinder must be of very good quality. In India itself it is more expensive than here. I am in the market for a wet grinder. Can anyone give me an idea if I should go for this one?
