Ever better than I thought!

This blender is everything I already knew I needed but wow. Using it validated what a smart purchase it was. The base is heavy and suctions to the counter and is very sturdy. the cup doesn’t feel cheap and has a nice weight to it. The no spill lid is a game changer and is perfect for taking my drinks on the go. I have only had the blender a couple days but so far, very happy with my purchase.

Good Product

Very good and the IQ blend is very helpful. The only thing I don’t like is when you put the lid on and want to use the straw the open side of the lid just sticks out. The design should have allowed for the lid to drop all the way down. Otherwise love the function and everything else!

Pretty in Pink 😍

I bout this to replace my old personal ninja blender that you push and hold the cup down to blend. This blender is GORGEOUS and I just love the cup and straw it comes with. Not only is it cute but it blends my morning smoothie perfectly every time! I will definitely be adding more cups to the collection. Do not hesitate to buy, especially if you want pink because they sell out freaky fast.

Prone to mold.

Beautiful and powerful, but handle has a little hole that lets water in, that makes it anti hygienic, and prone to mold. I am not sure if I am keeping it just because of that issue. There is no way to clean or dry that part. I am concerned about mold. Ninja should fix the issue, and also create smaller cups for nuts and grinding, like previous model.

Great blender!

I’ve been using this blender for about a month now and I’m very happy with it. It’s big enough for my morning smoothies, strong and powerful enough to blend fruit, ice, etc. The process is easy and fast; and cleaning is much easier than my previous blender. I’m definitely happy that I made this purchase.

Disappointed

Just used this for the first time yesterday and so far, worked well. Just disappointed in the color as it was different on line. I wanted to leave it out on my counter top to match my other accessories, but the color is really ugly. I would like to give it a higher rating, but am disappointed. My Ninja coffee maker in the light blue was perfect as viewed on line, but this was not.

CUTE AF and VERY STRONG!

This is a cute blender that has power! You can make a frozen smoothie with nuts and powders and it blends up just fine. It packs the same power as my Ninja Foodi Food Processor and chops up ice and frozen fruits with much ease! My only issue was a little water got into my cup handle but it dissipated. I wouldn't leave it soaking in water, I just wash it when I'm done.

Super Convenient

I’ve been using this almost everyday since I’ve bought it and I’m in love. I find it just really convenient for everyday use. I just put the ingredients in, walk away while it blends, and then come back switch the lid and I’m out the door.

Best Smoothie blender

Love, Love,Love this blender! Easy to use and clean. Precise results in a minute. My only complaint is that the tumbler is small. I would like the option of a 32 oz. Tumbler. Please give the option.

Cute and powerful

[This review was collected as part of a promotion.] Ninja BlendBOSS™ Tumbler Blender with the 26oz Travel Tumbler in the Watermelon Bubblegum color is super strong and works incredibly well. It crushes ice with ease and blends smoothies and shakes perfectly smooth every time. The motor is powerful for its size, and the blend-and-go tumbler is really convenient for busy days. On top of that, the color is fun and eye-catching. Easy to use, easy to clean, and built to perform—definitely a 5-star blender! 🍉💪
