Purchased this for the wife and she absolutely loves it. Her words best blender she has ever used.

This blender save tonnes of time in the kitchen & it really easy to clean either by hand washing or dishwasher. The blades are extremely sharp so don't be distracted when playing around or cleaning these. I keep the blades well away from kids reach

I love this blender. It is incredibly sturdy and quick, I use it pretty much daily for different smoothies. I use frozen fruit all the time and this baby never struggles. It is quick to clean and extremely functional. I am probably not using it to its full potential... It came with several books that has hundreds of healthy recipes.
I had a nutri bullet in the past but this is by far the best blender I have ever owned.

The Nutri Ninja is the best blender. This is so much better than the nutra bullet because the motor does not burn out and it has different speeds and sizes. I have done so much with it including soup bases, fruit juices and healthy smoothies

I use this machine 2-3 times a day for pureeing meals. I love this machine but I also have a similar problem with leaking from the nut under blade. Machine has also been getting louder. I have gone through 2 extra cups because of machine jolting and chipping edges.

Love this machine. The blade from the blender is a bit messy to clean. Watch out for your fingers if you don't have a dishwasher. Other than that, three different sized cups to blend your smoothies and the blender to do the rest...not bad. Bought this in mind for making purees for our child. You can leave the food in the smoothie cups, place it in the fridge and take it out when you want to feed the child. Minimal mess.

I use this daily, machine makes fast work of frozen berries and bananas. easy to clean. But, liquid is leaking from around the base shaft where the blades turn. Getting worse (more product leaking out). Received as a gift 6 weeks ago. Already spoke with company, they were nice and sent me a replacement base cap, after 4-5 days, it started leaking. Not sure what to do now.

This thing is fabulous. Smoothies, juices, soup, pesto, cocktails... Makes a mean margarita

Received as a xmas gift. Boy does this beauty blend. Noisy bugger but veg and fruit come out creamy with no need to strain. Cuts through ice without effort. Had to stop putting it away as it's used everyday. Simple to clean and set up. Highly recommended.

I only bought this last month as I need a more powerful blender. It certainly did not disappoint with power. I use the smoothie blade every
morning and the blender blade for preparing evening meals. Having a motor base that can blend, pulse, chop and liquify has made healthy eating easy. Best blender I have owned so far! Bought an extra 2 year extended warranty for $30(3yrs in total) from JB hifi.

Love the blending ability for smoothies, using ice, copes with lots of diff textures of fruit, veg, nuts. I wouldn't be without one, wish I'd had one long before this. I've had other cheaper blenders that are not as strong. Purchased this almost a year ago. We find it a bit noisy, but that's to be expected, with the job it has to do. We use it several times a day. I love the big jug for blending soups, when cooled. The smaller units are great for washing easily and drinking out of same.

I purchased this model because it has a 1500 watt motor. It blends ice in drinks with ease and with the correct proportion of frozen blocks and liquid makes a fabulous pina colada or strawberry daquiri slushy, amongst other things. There are 4 different size mixing bowls to suit different jobs. Yes it is noisy when blending ice, mainly from the ice blocks hitting the blades and container sides which is to be expected. I am happy I paid a bit extra to get this higher powered model

Love this machine! Make all my babies food with it and daily smoothies for both me and my partner. Can be a little noisy but not even an issue!

I bought this to replace my aging Braun. It's quieter than the Braun. Easy to use, easy to clean and bends my smoothies fantastically.

UPDATE MAY 2018
After just 18 months of occasional use the motor started burning one day when my wife was using it. It now does not work at all and is out of warranty! NOW DEAD.

Disappointed, it doesn't give me a nice smooth drink, it is always lumpy.
It looks well and washes easily but trying to assemble it is very difficult. The blade and container have to be just in line otherwise doesn't locate properly, the same applies to the motor. I have only managed to locate the two successfully in over 6 months use. I usually end up with juice splashing everywhere or making a pool. Would go for another make if I buy another. I fell for all the advertising on TV!

I have the 1500w set with also food processor bowl. Everything works great with the preprogrammed buttons. Got a great deal at Good Guys, paid less than $300. But OMG it is loud beyond imagination. Like a powerdrill going through concrete. I wrap it i a beach towel to muffle..

This is a great blender & although an expensive purchase, all components are of a very high quality and it performs as well as you would expect for the price. Dishwasher safe & easy to clean, liquids do not leake into the unit as it is well sealed and the attachments all fit securely. Noisey but powerful, and has added features such as a suction seal to your benchtop & detects if the jug pourer hasn't been closed properly before operation.

I purchased the Nutri Ninja Duo Auto-IQ Pro BL642NZ from Big W (was on special) and this is the best blender I have used. It is powerful, very versatile and easy to clean,
Just a word of warning, do not do as I did, I took the lid off the large blender to pour out the contents but did not remove the centre blade stem first and as I tipped it over the blade became detached and struck my thumb (required 3 stitches) I then read the safety instructions ( I'm a typical Male) to find that it does warn not to do that.
The power of this thing is great, ice and solid vegetables are no match for this awesome beast, do yourself a favour and check it out.

Received this beauty for Christmas and went above my expectations, so far I've only used the blender to make smoothies but blitzed them like no tomorrow. No chunky bits left at all. Once ive tried out the processor I'll write again, but so far extremely happy with the blender.
The machine itself is quite noisy but no more than any other brand domestic blender.
Thumbs up!

Omg I never never used a blender like this. Would highly recommend it to all my friends and family. Wish I brought one ages ago. My smoothies with real fruit and ice arnt lumpy and I can drink through a straw easier. And cocktails OMG!! Excellent for cocktails go and buy yourself one today
