Great buy!

[This review was collected as part of a promotion.] I bought this blender as a replacement to an old, old blender. It's such a revelation. I couldn't be happier with my purchase. The variable speed option is a game changer and the motor is so powerful while being quieter than others. I really like the small footprint of the machine too as well as the ‘add ons' I purchased. So easy to clean as well.

Fantastic High Quality Product!

[This review was collected as part of a promotion.] Bought this as a monthers day gift for my wife as she is loving her smoothie making and she absolutely loves it. I used the FREE engraving to write a lovely message marking the occasion and year too which was an amazing added extra. We wanted a very quiet blender (which is hard to come by) and this one certainly ticks that box. It also has a very sturdy and strong construction, not cheap and nasty like many other brands. The controls are also very simple and user friendly

The perfect Blend!

(This review was collected as part of a promotion.) So far I am loving this blender! It's been quite some time since I've owned a blender and I don't remember them being this user friendly. I sure appreciate the preset options, it takes the guess work out of it. I've used it quite a bit since receiving it. It's easy to use and easy to clean. My iced coffee drinks and smoothies come out like silk! A recipe called for crushed tomatoes - I had diced......a few pulses in the blender and crushed tomatoes it is! I don't usually have appliances sit on my counters but this is aesthetically pleasing and used enough to warrant a permanent place. It gets confusing with all the blender makes and models on the market today, but the choice was easy. I chose KitchenAid because I believe this blender will be around for years to come.
