Has anyone ever used these?

Nope. Seems like a bad idea that causes more problems than it solves.

[solspirit]

Why do you say that?
I don't really think there's any problem with good pins but this seemed kind of cool and I was wondering what it would do for the sound.

[v8stang289]

I have no experience with them, but they kinda look like they would raise the fulcrum point of the force exerted on the bridge by the strings? which could possibly cause problems down the line.

The anchor on the bottom would probably mitigate that, But I'm not sure

[solspirit]

Yes and it would also raise the action right?

[Condemned soul]

Read the reviews and noted there many favorable comments.

[Mincer]

I looked into them, but ultimately went with TUSQ pins. I couldn't find any definitive evidence that they significantly improved the sound, and read several reviews which said that strings could and would pop out.
That being said, I welcome any improvement here. The acoustic bridge is sadly still (mostly) relying on bridge pins. My Adamas uses a pinless bridge, which really should be the standard these days.

They wouldn't raise the action

The bridge and. Nut dont move
The action should remain the same

The break angle over the bridge could make for a softer feel on the strings

They look like they would want to twist under tension
For that reason, I'm out

[beaubrummels]

I don't break or need to change acoustic strings often enough to require quick change end pins. Seems like the wrong way to apply tension to me, but I don't really know.
