May I ask when you say perform an eb, is this telling them that when I opened the box all the contents were intact except the mouse?

Correct.

What method was used In the first SE?

I just went on live chat with Logitech, told them my mouse was having cursor issues (randomly stop working etc) went through troubleshooting, gave them all of what they asked of me (serial numbers, video of the cursor issue), and they approved of a replacement. I was surprised they did not ask me to destroy or ship my current mouse back to them.
