I have bought and tossed several blenders and chased down top rated blenders from consumers tests only to be disappointed. The Braun Jug Blender MX2050 is the best I have found. I bought two. The sound and feel of the smooth whir of the  powerful motor is alone worth the price. It has a solid glass blender "jug" with integral glass handle, no metal bands held on to a plastic handle with screws to come loose or break. It has a substantial tight fitting lid with heavy duty gasket and a plastic access port on top which actually twists tightly and securely into place between uses. There are no dozens of wobbly push buttons on a control panel all impossible to get clean with obscur legends such as real slow, faster, real fast, macerate, grind, etc. There is just one knob with a firm feel, audible click and pointer to five positions labelled intelligently 1,2,3,4,5. The motor switch has an interlock with redundant microswitches which guard against a runaway motor in the event the jug is not firmly mount on the motor base The product design is elegant with understated curves gracefully soaring to a complementary colored cap. I feel good all over every time I make a smoothie. The blades have no trouble attacking large strawberries frozen rock solid and then at high speed whipping air into the whole contents for a frothy texture. Buy one and register your approval of sound engineering, common sense product design and top notch performance
