Review on Compatible Replacement BL682 30 BL642 30 BL687CO 30 by Gregory Flynt

My original blades still work but the silicone ring has turned black after 2 years of sloppy washing by family members. There are no good replacement rings at Revain. They all have a terrible fit. The only place to buy OEM replacement blades is the Shark Ninja Store and I won't pay $46 when the entire kit is only $120. I was bothered by the negative reviews for this replacement blade, but since 75% of customers had a good fit I figured I'd take a chance. It fits perfectly. After 4 weeks and 15 mixes it's still working great. Although the blade is already as dull as the original 2 year old blades. Included is a replacement silicone ring that revived my old blade assembly. Now I have two working blades.
