Bought a Braun MR 4050 HC as gift, and this one for my own.
I give five star for this product - the Braun came with a beaker, a chop, a whisk, a blender - just the same as this one. However with a few pounds more you get a lot extra.
Most noticable is the metal blender which mean it is SAFE to use in hot soup or liquid, whatever you want. You also a get filter to make very fine drink. Another obvious advantage is the 4 speed setting, i use speed 1 and 3 at most time and found it adequate for most job - if I want to do it quick I use 4, and 1 is very good whisking eggs or a milk shake.
YES, some blender offer 400W and this one is only 300W. I have tried both, and I can tell you I could not notice the difference. The only drawback: This thing is heavier than a Braun hand blender, however you are not going to hold this for an hour, are you?
