TR in the US makes sockets harder to use, but I have never heard anyone complain about TR in the UK, as the earth/ground pin is always present, and is physically longer than the live and neutral, so mechanically it is reliable and unnoticeable.

“Just baby proof” means remembering to keep those little plastic covers in place in every outlet. That doesn’t seem like superior usability.

I was talking about TR in the UK. You have to push it just right, it's noisy, and you have to use force.

That’s not my experience but it’d be interesting to from others on the matter.
