Does anyone have any evidence that these are bad news or just hearsay?

Thanks, everyone (I think!) When I first started doing this, I thought that push-ins were agreat idea-fast, less space, etc. I always gave a tug to check, and then about a year ago, 2 receptacles failed the test with barely a pull. Avoided them ever since.
