However, the item is of a robust quality, it came with the adaptor for other models of nutri ninja, and came with an extra seal.

1.0 out of 5 stars Worked well for a while.

This worked well for a couple of months then the bearings failed and it no longer sealed and also leaks some rusty looking liquid. The blades now wobble back and forth. The original part lasted for years and years. This one barely a year.

1.0 out of 5 stars Should Be Banned — Total Health Hazard!

D.S.M. · 27 April 2025

This product is a complete scam and a serious health risk. After barely a month of light use, the blades started leaking a foul, grey sludge that smells like burning chemicals. Absolutely disgusting.This is not just cheap — it's dangerous. Whatever is leaking out could easily make someone sick. It’s shocking that Bolo even allows this junk to be sold. I wouldn’t wish this trash on anyone.This isn’t a blender blade — it’s a lawsuit waiting to happen. AVOID AT ALL COSTS!

5.0 out of 5 stars Perfect replacement for my ninja

The original one was making some really harsh sound and water had started leaking.Impressed by how good it was. saved me buying a new ninja!

2.0 out of 5 stars A good replacement to begin with - but poor quality.

L. · 16 May 2024

When I first got this product back in January I was impressed - i'd had the original blade for about 7 years with daily use. It had been leaking for a WHILE, so it was great to have a fully functional blade/lid again - this one fits great, looks identical to the original, and came with a replacement seal.However, the plastic part of the unit started cracking after about 2 months, and leaking oil/blade fluid into the base after 4 months. £12.50 sounds reasonable, but with the apparant huge quality difference, the replacement blade direct from Ninja (at £20) isn't so bad. Sadly they are out of stock and I imagine since it's an old model I might be stuck with these ones.

A Second Wind for My Decade-Old Blender

(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Let me just say, I didn’t think my trusty Nutri Ninja, which has been blending up smoothies and questionable late-night concoctions for almost 10 years, would live to see another day. But this 7-Fins Extractor Blade Assembly swooped in like a superhero, saving me from shelling out for a whole new blender.The blade is sharp, fits perfectly, and works like a charm—my 10-year-old blender feels practically brand new! The rubber gasket is snug and leak-proof, and it handles frozen fruit and ice like a champ. No more weird squeaks or the faint odd smell that I was trying to ignore.However, let’s not pretend it’s all sunshine and rainbows. The price had me raising an eyebrow (hello, it’s just a replacement part), but when you factor in how much a new blender costs, it’s still a win. Also, with the spare gasket, you can't go wrong.Overall, this replacement part has breathed new life into my blender and saved me from adding another appliance to the landfill. If your blender is old but gold, this replacement piece is totally worth it. Blend on!

Check your model number to be sure to get the correct ones.

Better than expected, they were exactly what I was looking for and they fit perfectly. Extra bonuses came in package, an extra seal and a pick to remove old seal. Highly recommend this product.

Works!

Totally works for the ninja blender and fit the standard blender mugs perfectly! Go for it!

Do not purchase, bad quality plastic

M.S. · 9 April 2025

Broke after a few months, there are cracks in the plastic. So used one and then started using the second, which has mostly broken as well.

Fits

They fit well and work with our existing Ninja.
