I had to look a bit for what I needed on the site, but once i figured it out it wasn't too bad. I got the product pretty quick and it was packed pretty good. I'm just glad it was the right replacement piece.
Easy to replace and I'm glad I found it. My main complaint is it should be made out of metal instead of plastic to prevent breaking. The MD website is a great resource.
The product had no diagram nor description for installation, but it was not difficult to figure out. It was necessary to consult the FAQ web page part way through the procedure to know that one needed to use some force to pop the cover off of the electric brush head.
Easy to install. However, I was distressed that the part fractured in the first place. Normal usage should not have caused it to fracture, but it did. It would be nice if a simple installation diagram was included.
Part was easy to replace however it did not fix the problem.
