We were initially considering a whole new blender, just because the blades had jammed up and wouldn't turn anymore. But I decided to check if there were replacement parts available, and sure enough, here it was! It fits our Hamilton Beach Blender perfectly.My only concern was that the blades are somewhat different from the original; see photo - our original is on the left, and this Blendin replacement part is on the right. None of the reviews mentioned any problems with blending with the new part, so I can't imagine it could make a lot of difference.We haven't used it yet, so there may be a further addendum to this review later. But for now, we are very glad to have found a replacement part and have not had to buy a whole new blender.
