I had ordered this part in Jan 2023. The old one is still working just ordering it in case I don't find it.
Yes it takes a bit of strength to put the blade in the motor slot and to remove it but it still works. I would rather spend $16 than $600+ to get a new blender.
I really use it from grinding whole spices to making baby food. I dont even have to strain the baby food it grinds it that well.
