Original part has click sound when u plug this part on the socket. This one does not fit on the socket and keep detaching. I seriously do not want to give even one star but cannot give 0 star.

This does not work at all. I am very unhappy with the results and I could not return it. I would not buy it. There are no instructions at all anywhere.

I bought this, it was cheap enough that I didn't feel like sending it back.  Do not buy this, it will not work.

It's pretty much not working. It's not popping the trash out as it is supposed to. I wish I didn't even buy it.
