Blendin24oz Large Tall Cup with Sip N Seal Lid Replacement Jar, Compatible with Nutri Ninja Auto IQ & Duo Blenders - Premium Blender Replacement Cups - Cup Diameter is 4" (2 Pack)

I was a little worried since the the walmart model CO101b wasn't listed but since it's almost identical to the SS101 I figured I'd give it a shot and I'm glad I did because it fits perfectly!Just as good as the original cups, tight with no leaking!

The cups are awesome! I’m not a big fan of the lids but not awful worth the purchase

Very good product

Love these. Fits perfectly, just twist the blade lid a touch more than you think and I’ve never had it leak.

Good price for 2.. and dit my older machine..

For my nutri ninja and it is great

Have been using daily form about 6 months. All of the seals are holding up fine. It been running through the dishwasher ar mid level just fine.

I bought this to have a spare for my ninja and is almost the same quality of the original I will totally recommended

These are great quality add-ons if you are looking to pre-blend and freeze or just need a few more ‘to go’ cups for kids or the roommate. They appear to be the same quality. I can’t tell the difference between the two, apart from the fact that these are off-brand do not have the Ninja logo etched into them.

Nearly identical to my original Ninja cups. I was initially concerned about the flip lid part but it stays closed fairly well. I throw them in the drink holder sleeve of my backpack and I’ve yet to have a leak or a spill. Only docked a star because the rubber seal squishes out when tightened. I ended up just not using them and it still seals well.

I prefer these lids as well. They are easier to get on and off than the name brand Ninjas (fibro), work just as well leak wise, and are easier to clean.

These work great for our Ninja blender - excellent replacement since we were not willing to pay triple the cost for what's essentially a cup.

Thicker shacks don't flow out of tumbler as well as original. Lid needs to be very tight when blending or it seems to leak.
