I own a Kitchenaid mixer, food processor & blender. Based on my excellent experience with the mixer I expected the blender to work to the same high standard, but alas no. The blades do not have sharp edges and I find, no matter how long you process soup, there always seem to be some lumps left, which you only discover as you pour the contents out, the contents having appeared completely smooth through the quality glass jug. As a Home Economist I am used to appraising equipment, and while this product is well made & looks good I am not sure it is fit for the purpose - making smooth puree.
It does crush ice and whip up batter well, but beware making mayonnaise. When you remove the the central lid from the main lid to drip in the oil, so much egg and oil spatter out that not only the machine and your arm but the surrounding kitchen require a complete scrub down on completion. A good design feature is that when you switch on, the motor starts slowly for a few seconds before engaging at full speed, this means the contents don't hit the lid with a great whoosh of impact. However, blending hot soup does seem to create a lid lift off effect as steam is whirred up. Let the soup cool prior to blending, only half fill the jug and always, as with all blenders, cover the lid with a cloth before turning on.
Other reviewers mention leakage from the jug, this only happens if the jug is not taken apart from the base each time after use, and it, and the rubber gasket are not properly cleaned, then ensure you screw firmly back in place engaging the thread correctly. This is not an arduous task, but one which is necessary with all blenders for health and hygiene - food clinging in nooks and crannies will grow microbes.
If you really want a blender that is the business, and manage not to faint at the price, buy a Total Nutrition Centre by the Vita-mix corporation (from America but available in the UK now). This gadget has a 2 horse power motor and can reduce a whole orange, skin and all, to juice in the blink of an eye. I guess this blender has dimmed my view of all others on the market.
Had I bought my Kitcheniad blender, and not been given it at a greatly reduced price because of my job, I would be very cross to have spent the money only to find it did not work as I expected. Do not however, let this bad review of the blender put you off the mixer, it is the best in its class. When I have had my Kitchenaid food processor for a reasonable length of time I will report on it, it is too new at the moment and people always write glowing reports about new items, better to wait and really see how they perform over time first.
