Blender Ascent Blade Assembly 105733 Replacement for Vitamix Blender Ascent Series A2300 A2500 A3300 A3500, Base Blade Part Fits Pro 750 7500, Explorian E310 E320 48oz and 64oz Low Profile Containers

They work great and last a long time too.

After a year of using my refurbished Vitamix Explorian E320 everyday one thing went wrong. The shaft that holds the blade to the gear broke off. I was discouraged to find out that Vitamix doesn't want me to repair my blender and doesn't sell the part (what's wrong with you Vitamix!?). They want me to buy a whole container (uh, NO!).Luckily this seller sells a reproduction (not genuine Vitamix) part that fit perfectly and got my blender working again. The blade isn't a genuine Vitamix but it seems to work fine and I could easily swap in my old one (105733-1) if I want to.And be sure to get the Vitamix nut wrench (#15596) if you don't have one. The nut would be impossible to get off without it.https://www.amazon.com/dp/B0028Y4CVO

This was returned. Original blades which dulled were still better than these. Decided to sharpen the original blades with a whetstone.

As the blender became noisy and less efficient, I decided to change the blade. Installation was easy using the special tool, available on Amazon. With the new blade assembly the blender now works like new.

Bearings are loud, blade is dull, doesn’t work anywhere near as well on frozen items as the factory blade assembly. I can’t make frozen fruit sorbet at all with it. It does technically blend, so 2 stars.

Purchased to replace my original blade, that was getting dull. This one is not as sharp as the old blade is now. It did sharpen easily with a file, but if you don't have one of those it may not meet your needs . Arrived well packaged and over night.

I thought my blender was a goner after a little accidental spoon mishap, but this replacement blade assembly worked like magic. The process of replacing the blade assembly was surprisingly easy – no complicated maneuvers or frustration. It fit perfectly into my blender, overall 5 stars

Does not blend as powerfully as original blade. Struggles even just to blend frozen bananas.
