Great smoothies but disappointed it leaks
599409
I saw other reviews saying the jar leaks, but one review said the leak issue was w/ the glass jar model, not the polycarbonate jar model...not true. We make a lot of kale smoothies and I was very pleased with how fine the kale was liquified. Ice and frozen fruit crushing ability was good too. But it seems when running on high speeds, the underside of the jar leaks. It doesn't leak excessively (yet), so I feel the blender is still usable. It just makes it a little messy to clean. Having known this beforehand, I probably would have tried the ninja.

This is a great blender for smoothes and protein drinks.  I did receive it with one of the cups cracked

Was very excited to make smoothies for my son for breakfasts and that lasted a few months and then the blade started leaking and now it makes a terrible mess everytime we use it. I'm about to throw it out less than a year later. Not worth it!

I want to love it but it does leak a lot unlike my adult version. I wish I listened to the previous reviews.

Love everything about the bottle except that it leaks out the bottom of the screw on cap. Every time I take a drink I get drops of water on my lap and the top is screwed on correctly. I had to stuff a Kleenex in the sleeve to catch the leaking water. If I was using this at the gym it probably wouldnt bother me as much but I am using this for work and that just will not work. Will be returning...

Loved this blender and used it for two years. Started drinking smoothies regularly about 4 months ago, and now the carafe is leaking. I was going to replace it with just another carafe, but the reviews are saying that the new carafes will continue to leak after some use.

My four year old loves these.  They are great for the smoothies we make for him as well as water or juice..  only issue, when held upside down they leak.  But we still love them.

The NutriBullet does a wonderful job totally emulsifying the food, but had problems with it leaking around edge.  We thought that it was missing the gasket but when we called Magic Bullet they helped us realize the gasket was there but you could not see it because it was the same color of the extractor blade.  They are sending us new extractor blades.  Hopefully they do not leak.

Ive had this about a month and half.  Ive used it quite a bit, and been pleased until recently the liquid Im blending has started leaking out of the bottom.  Messy and annoying

I use my blender daily and here is what I found after a week of use.  It makes a nice smoothy but not unless you open it several times during the cycle to scrape the sides.  The locking cap is nice but it collects water inside when you wash it.  I made pancake batter this morning and when I poured the batter into the pan the water dripped, hit the hot oil, and splashed it on my hand - ouch!  I also noticed water and condensation in the handle.  I know it is just water but is this a potential bacteria growing problem - scary thought.  It wasn't cheap so I did expect better quality. I also found it difficult to hand wash. I will need to buy a different cleaning brush/ sponge to get into the bottom.  Overall it does blend stuff nicely.  My smoothies do not separate even after many hours in my lunch bag or refrigerator.  I think I am returning this as the bacteria thing scares me.

Hi.  I am enjoying the 7 piece meal prep. I started this life changing healthy eating habit and they're working for me.  There is one small issues with the liquid like (juice from pickles, etc ), leaking a little from bowl.

Leaks a bit and the motor has an 1/8 or so play, friends model does the same so I guess that is normal for this model.
So after use I always wipe it off and before I start the blender I hold the blender with one hand so it does not move.
I expected more from kitchen aid but it performs good, I like the soft start and it is way more quite then my old mixer.

i received my bottle and was very excited to use it, i filled with fruits and put on the cover and turned it sideways only to realize that it is not leak proof. I am so disappointed

Even though they are original Kitchen Aid parts, they must have some sort of defect. The first one I ordered from a different seller had one of the blades too bent that it was scratching the bottom of the pitcher and also was leaking when blending just a smoothie and didn't use any frozen fruits. The second one I ordered was better but still leaks (in a much less scale than the first one). Since the blender I have is almost 9 years old, the investment was good but probably could get a new Kitchen Aid blended for twice the price of this pitcher and you'll know for sure you get a 100% guaranteed product.

Everything about these cups are wonderful. My kids needed new ones and the designs were what they wanted unfortunately the moment my son leaned over cup in hand his water came right out. Idk if I got 2 defective cups bc my daughter's did the same but I am not happy at all with the fact they leak!!

Awesome texture, keeps drinks cold, but don't tip..it leaks horrible. Bought for my son and packed with ice water for beach. By the time we got to destination, all the towels in the bag were soaked. Tried again, ensuring top was tightly sealed and inner straw securely in place, and the bottle still leaked over everything. Dissappointing. I very much loved the feel and color of the bottle, but I needed a true leak proof bottle.
