Ymkf Sqqr 2Pcs replacement blades for blender, blade parts compatible with nutribullet pro 900/600 series

I bought two blades for future use 6 months ago. I put them away in the original package. I just took them out and used them today. One blade unit has a fissure in the base (crack) and leaked all over the place. I should of looked when I got it but I didn't. I wish their quality control was better. This wasn't a shipping issue, box was in perfect condition. I'm sure it's a manufacturing issue BUT I'm out two blade unitsCorrection to all above!!!! Now the other unit cracked. I would not buy from this seller

So - the first time I used the new extractor blade it burned up my 2 year old Nutribullet motor. The extractor blade and base look identical to the one that was replaced and the blades spin freely. I don't know what caused this and it could just be a coincidence. Unfortunately it was an expensive coincidence. I just bought a new Nutribullet Pro for $99 so these extractor blades are headed for the trash can. Bummer!

These replacement blades are sold by several vendors on Amazon. I've purchased a half dozen over the last couple of years. They're hit or miss. Some have the bearing seize after just a few uses forcing you to wear hearing protection or leave the room. The first one of this pair has made at least 25 smoothies - more than I'm used to. Wish someone would use a quality sleeve bearing - I'd pay $40 for it. Then I wouldn't have to keep buying these cheap ones.

My original blade finally died, so I got these. They looked different, and one of the main differences is where the rubber ring goes... There's an indentation in the plastic it sits in. The blades look a little different too. I've been using the new blades for a few weeks, and love them! It seals better than the old one, so I don't have as many leaks (only had one or two), and it works quicker. Cleaning the rubber seal is nice too because it goes back in way easier thanks to that indentation. I'm really happy with my purchace! I use it almost every day to make shakes.

Broke two Nutribullet blenders before we realized it was these blades. First blender we had for 5 years and it saw daily use so we just figured it was time. We had noticed the noise (mentioned in a lot of other comments) and then one night the blade started smoking, leaked black goo into the shake and the Nutribullet never turned on again. Bought another and tossed that now broken blade. Two weeks after purchasing the new blender, the same exact thing happened, smoked, leaked black goo, and broke a brand new blender. Really upset that Amazon sells these. DO NOT BUY.

Great fitting blades and the price was fantastic especially for a 2pack.blades are nice and sharp and secure tight fitting excludes any leaking.yes buy em.

The blades arrived quickly, and work as expected in my machine. Sharp blades make such a difference in how quickly I can blend my smoothie.

They seem to work well, but it was disappointing that the rubber seal became twisted aroundthe blade while in use one time. It took a chunk out of it, so now I can only use the secondof the two blades. Bummer. : (
