Bought this to replace our food processor which had started to leak. We like the automated functions which means we can do something else whilst the blender does its job. Smoothies are good. It is very loud though

As a blender this is amazing. Blends really well - it did take me a few trys to perfect what sort of blend I wanted for my smoothie, but that’s to be expected (my last blender only had one option) Looks stylish, can leave on the counter without it looking messy. Perfect blender. My issue is with the bottle - again it looks stylish and is a very useful size. However water gets inside the lid whenever you wash it, and is impossible to remove. Plus using the straw that’s provided means you can’t close the lid - this limits the bottles usage.

I bought this after my Breville active went wrong. The blade strength is its best feature and I like the stone colour. I find the cup too heavy and clunky and a bit of a faff. The straw is also a bit ott and difficult to clean. It doesn’t fit nicely for travelling in the car and drinks aren’t as easy to make in comparison to others blenders I’ve tried. It’s also very loud. A good product but depends on your needs and preferences as to whether it is good value and a good buy. I would return if I could
