Works Great
Watched the video then Installed the foam replacements on my very old Radio Shack Optimus bookshelf speakers. The process was quick and easy. Let the glue dry overnight and was using the speakers the next day. The glue got a little tackier faster than described in the video but, everything worked out fine. Just make sure everything is ready and within reach once you start

I was able to easily find the part I needed and viewed a video on how to do the repair. I promptly received the part and I'm happy with my first speaker repair job. I've recommended you to others and will be reordering soon for another pair of speakers I own.
