Watched your very helpful video...gave me the confidence to tackle it myself...so, ordered the part. Matter of fact you had a great price so I ordered two...same shipping charge for one or two!
Read the directions when I received the part...it took a bit longer to release the old piece than stated (found that a heavy-duty, short-handled screwdriver worked best), but mission accomplished. Attaching the new coupler was really easy.) I'm so happy to have my smoothies back again!!
