Spencer Doyle Ninja Blender Replacement Parts Ninja Bottom Blade 7 Fins and 1 Gasket Rubber for Nutri Ninja Auto iQ BL482 BL642 NN102 BL682 BL2013 Nutri Ninja Blender Auto iQ Blade (Blade 7 Fins)

This is very similar to the original Ninja blades and after the 1st use I thought it was going to be a great replacement. However, on the second use I noticed liquid had run through the seal around the shaft of the blade and left some residual in the base of the blender. I gave it one more try and the issue only escalated not just leaking a little but enough that it ran through the drain port in the back of the blender base and all over the counter. I'm going to be returning this failed part immediately.

This is a decent replacement for the Ninja blender blade assembly. The original part’s bearing overheated and leaked nasty stinky gray liquid into our smoothie. The motor couldn’t pulse correctly either with that happening. I didn’t want to spend a lot of money to get it working again. The NutriNinja is very convenient for whipping up smoothies but I’ll never buy another one because the largest cup also had a problem. The plastic nubs wore down so it couldn’t lock in so the machine would run. I wasn’t spending the money for a replacement cup and just made do with the smaller cups ever since. I gave this part a 4 rating because it hard to screw down tightly on the cup.

Hello,I hope the supplier can contact me, I bought these 6.5 months ago and now my product is leaking from the bottom and I don't know how to do, I do not what is the warranty period but I would like to give to Spencer Doyle a new chance to convince me to bought my repair part with them,I need to say that at the beginning was working fine with problems to lock with the ninja but I can support that... but now is worst... is leaking and smells like something is burned everytime I use.Thanks

I read the reviews before I got my replacement blade. I didn’t have any issues with leaking. I found mine to work great. I do hand wash my blades. I have found every time I put mine in the dishwasher, it’s only a couple of days and they seize up. For me that’s seems like that is how I ruin them.

This replacement seemed like a good purchase initially as it worked fine. Two months later they are leaking and have caused issues with the base unit. If you look at them very carefully it seems like the blades are not exactly the same as the original unit (which is still working fine, we just wanted more of them) and they cause our base unit to squeal loudly when we use them now. I have to think it is work paying up for original parts in this case if they are available.

This can't go in the dishwasher or even get wet on the drive blade side. The water gets directly into the bearing like there is no seal. Then the bearing goes bad and it makes an extreme amount of noise when you use it. Wear ear protection!!

Arrived from seller super fast. Seems like a good product. Came with 2 gaskets and its working great so far.UPDATE: Only lasted about 3 months. Blade assembly seized up and will not freely spin. Causes blender to run under a lot of strain and makes a terrible noise.
