Hi author, let's see what you have.
Your formatting is really strange. There are awkward line dividers everywhere and fonted words cluttering up the article. I don't really understand if this was your intention, but there are testing log templates available for what you are trying to pull off. As it is right now, it just looks like an unjustified format screw.
In regards to the actual concept, I can't really say I enjoyed or understood it. It sounds like a button that does…something… to people. Honestly, it really bothered me that your description only goes into its indestructible nature but then becomes extremely vague when describing its effects on people. In universe, the description is where readers can get a full, yet brief, understanding of the SCP and its capabilities. Even in cases of evolving SCPs, the description is typically edited to account for this new information.
I recommend bringing this concept to the Ideas and Brainstorming Forum. Make a paragraph summary of your SCP and ALL its abilities and work with the other users there in making a refined, engaging SCP. They'll be a great help and they'll also help you find what aspects of your SCP can be salvaged, and which aspects bring down your piece. Good luck.
