Stainless Steel Blender Blade with Ring Seal Gasket Compatible with Black Decker, Replace 77666SS BL300 BL450 BL500 BL300 BL450 BL550 BL600 BL600B BL700 BL500 (73.25mm/ 2.88inch)

Even though the manufacturer (Black & Decker) says the part isn't available anymore, this item is a clone, and a perfect fit in my 16-year-old blender. (I also love spending less than $10, rather than buying a whole new blender.)

I did the math and after ordering this one second, it fits my HB Stay or Go blender, and works great. There was a product I tried that said it was for HB, but it was too small. This one is 2 7/8 inches, and fits like a glove. Great product, seems very durable given the materials it is made from. Will have to wait and see on the longevity, but happy for now, very happy.

Great replacement blade for your blender

This product works fine for our old Black & Decker ProBlend BL 600 blender. It is neary identical and looks durable. The rubber ring is not quite as thick as the original. IMPORTANT NOTE: Like a previous customer mentioned, this item fell apart when I opened the box. For a while, I couldn't figure out why the nut did not screw into the blade. I thought it was defective. But then I realized that the nut is threaded in reverse. It screws on opposite of my expectation. I think that is because the blade swivels in one direction and the assembly is such that it won't loosen when the blender spins. Anyway, that's my tip -- which might be obvious to everyone but it wasn't for me!

I bought this to replace a piece on an older Oster blender. I read lots of reviews and pick the best one that I could and it worked it fit.

The parts seemed to be of good quality but they were not put together. If I could see that might not be a problem but in this instance I just want to get my money back

Does not fit on my blender

Good deal
