Question: Why does my Cuisinart blender leak?  I replaced the gasket and it did not help.
Document: I am very satisfied with the Cuisinart Blender Blade & Gasket I purchased.Shipping was very fast and purchase transaction went very smooth. Glad to have my blender/food processor back in working order.
I'm so excited to share that the Cuisinart blendar my husband got for me when we got engaged in 2006 is now working again. We replaced the blade and it's blending everything perfectly now.
This was a replacement for an original cutter blade that cracked after years of use. This part fit perfectly and restored like-new blending and chopping to my Cuisinart blender. It even came with the rubber gasket.I'd recommend hand-washing the blender base and cutter blade, since the original one probably cracked due to the drying heat of my dishwasher. Just be careful, though, since this thing is really sharp!Great replacement part to keep your blender working like new. *** Update after 4 months of use ***The cutter blade is having similar problems as my original Cuisinart blade - it's starting to get really tight in the shaft (huh, huh!)
Since I was able to get this part, I was able to save my Cuisinart SmartPower Blender (BFP-703 Series).The part arrived fast and was very easy to replace. It even came with the washer that others are selling separately. While I'm still looking at eventually upgrading to a really high end Vitamix or similar blender, this was able to help me prolong the life of my once $100 blender. I used it tonight flawlessly. Very pleased.
Replaced my locked up blade and blender is as good as new. Would buy again if I needed another blade.
I believe all replacement part for this expensive blender are now of the worst quality ever! This is the second blade I have replaced in less that a year.Not sure if it is because they are &#34;made in China&#34; but certainly this particuar part lacked quality control. The blades wer dented and the bottom part broke aftter very few uses.
No better than the one I replaced. It still binds up after using it for a while. It works, but it is hard on the motor. I wish they would redesign it.
Great shipping and a great product.Received the rubber gasket as well, which was unexpected,so thanks for the  bonus.I will probably be ordering another one within a year because that's about how long this blender blade will last before it seizes up.
I purchased this blade after I had a mishap with the existing blade I had. It fit perfectly and didn't leak. It was definitely better than having to purchase a whole new blender.
I can't remember how many of these I have purchased. I wash them in the dishwasher and they eventually crack along the shaft. The rest of the blender is fine so I figure it is worth it to just replace this part when it breaks. My blender gets daily use making protein shakes. Came with a gasket, but they never seem to go bad.
Answer: Ours started leaking through a hairline crack in the shaft of the blade assembly. I've replaced two in the 9 years we've owned our Cuisinart blender.  Both times for the same reason.  This new one seems substantively sturdier (fingers crossed).
