DSYJ16 Ounce of Blender Cups & Replacement Parts Single Serve Cup Compatible with Ninja BL770 BL771 BL772 BL740 BL780 BL660 BL663 Professional Smoothie Blender | 2 Cups & 2 Cups Lid

I originally bought these at the end of March and by June they were completely warped and oval shaped they also don't stand properly - the blade attachments and lids do not fit properly after washing them in the dishwasher. This is the exact listing I purchased from and has now been updated to say "generic" when I purchases they were $30 and marketed as Ninja brand, logos and all on the cups. My original single serve cups that came with my ninja are two years old and in like new condition. The quality of these does not withstand time like the authentic ones. While I'm glad they've updated the listing to reflect they are not authentic Ninja cups, I'm so disappointed in my purchase and wish I wasn't past the return date because I was totally ripped off! DO NOT WASTE YOUR TIME OR MONEY! Go to the ninja website to purchase additional or replacements cups, a set of 3 is under $25.ORIGINAL REVIEW: (after 1 week of use)Excellent quality - Ninja Brand. I was in need of an extra set of single cups for my morning smoothies and couldn't beat the price. I also like that its another color option to the black lid and greenish tinted ones that came with my Ninja. If you find yourself washing your cups daily grab another set - makes life so much easier!

These cups have sip lids, but dont seal like my original cups. I am looking for cups that fit my BL830 and have Sip and Seal tops like the original cups that came with my BL830. The BL830 has 16oz cups. I dont care if they are 16, 18 or 24 oz. I mainly want cups with Sip and Seal lids (like my originals) and four tab rims that will fit my BL830 base/motor.

I was looking for two new smoothie cups when I came across these. It works great with my Ninja smoothie blender. A few features to call out...unlike my original cups, these did not come with a mark for 8 oz and its hard to clean by hand the inside bottom of the cup. The upside? The price and I like the cup lid. It only has an opening to drink from. It works.

These cups are horrible. I bought two packs and all of the cups are defective. The lid looks and feels like it screws on but it doesn’t. When you attempt to use them, the lid leaks and it ruined the expensive blender... it’s completely dead. Not worth the money when it destroys the blender and you cannot return after only having for a couple of weeks. I would give them less of a rating if I could!

I am returning these cups because they lost their shape the first time I washed them TOP Rack in my dishwasher. They won't fit the blender blades or the tops. This must be a knock off product. I'm now purchasing from the manufacturer. NOT HAPPY.

This item was delivered to me on July 19th I am now trying to return it one day later on July 20th and it says I can't return it cuz it's been over 30 days. What the hell!!! These cups do not have the snap lid like the other ones so you can shake your shake so I don't want them. The picture is deceiving because it doesn't show you that they're open mouth.

So while these are the same as the cups that came with my blender, for some reason the lid is very difficult to get on and off and so is the blade. It's like the wrings don't line up properly. It works, but it's just kinda frustrating.

These are technically the correct cups for my Ninja, but the mouth and the threads are not sized right so to make them work you have to crank them down really tight so hard my wife can't do it herself. It gets worse after blending its even harder to get off so that I have to use a rubber band to get enough grip to remove it. I've stopped using the new pair and just use the old cup for both of us.
