I am very happy with this blender. It is so easy to attach the top part, no twisting or turning to get it just right. Multiple measurements are listed on the outside, ounces, liters, cups, making it very easy to see exactly how much you have. Great selection of buttons for everything you could possibly want to make. Dishwasher safe makes for easy cleanup. I would recommend this blender to my friends and family, it is a great buy.
