We really liked the blender and had no issues until the base cracked after just 3 months. I was going to repurchase the same model, thinking it was just a defective unit, but then read about this happening to a lot of people (on another site).

I bought it 3 years ago with 3years warranty. It's a good blender, I used it most of the time to make my smoothie but it's pretty loud. After the warranty expired the cup started to leak so I contacted Sam's club. They refunded me and I kept the blender so I'm trying to find a cup with a new seal.

I wish Sam’s Club could get this model of the Nutri Ninja Auto iQ Blender back in stock. I would love to buy more for gifts. It makes delicious smoothies, perfect crushed ice for a sno-cone, slushy, and so much more. I love the different speed options. I love my Professional Nutri Ninja Auto iQ too!

I have the Nutri Ninja for a couple of months and it is great. The Auto IQ mixes up smoothies perfectly. You do have a use a little extra ice to have a thick smoothie as this machine does some serious blending. The Ninja is awesome and will mix up any fruit blend magically.

I have had this blender for three weeks and it has quit working correctly. I try to blend a simple milk, banana and protein powder, not even anything frozen and it shoots liquid out of the bottom leaking all inside the machine and all on my counter. It doesn’t matter what you blend it leaks. It worked great for about two weeks. Those of us who have to save money to buy this cannot just go out and buy a new one, shame on you for making such junk!

After using this for a dozen or so times, I can highly recommend. Makes amazing smoothies in only 45 seconds.. No seeds or pulp. Make sure you fill the cups in the correct order. Always put ice and frozen fruit on top before you screw on blade assembly. Don't pack it. It is loud.

I purchased this blender hoping that it would be better than my Hamilton beach blender just to be disappointed. It could barely blend frozen açaí. The blades kept getting stuck in the frozen açaí. Needless to say, it was a waste of money.. Especially since I have to take the cup out of the holder and shake it in order to get it to blend properly.I’m doing most of the work.

I have a blender but wanted processor specfically for making nutritious and diet smoothies. Quickly moves all fruits and veggies to a great smoothie. With the three travel glasses I am able to mix one up and head out the door to school. I am also tracking calories so I know the caloric and nutrition value of what I am drinking. Great purchase.

The Nutrition Ninja Pro BL455 is quick and convenient. I've used it almost daily since purchased three weeks ago. It is easy to use and blends well. Cleanup is easy, as all the pieces are dishwasher safe. I haven't use the recipe book yet. The Ninja was an excellent value as I purchased it on Black Friday.

Very loud (needs soundproofing). Nice auto features and 3 size cups. Blade assembly fits threads on the outside of cup. Questionable design: spout lids fit threads that are inside the cup; those inside cup threads are coated with the smoothie after removing the blade assembly.
