Product rather convenient, easily stored in a refrigerator, dishwasher-safe. By cons, for the upper part (whip + mechanism), we can say that the quality is not there. This lack of precision in the gears and it seems that the system will drop, crunches and jolts when "mixing" the ingredients. Conclusion: okay but lack of quality in components, which is becoming increasingly common these days. The products cost less and less, but the quality drops even faster. Buy, is very expensive, as there is more good quality products, we must resign ourselves.
