Hornady Lock n load Die bushing

Does anyone have any experience using Hornady lock and load die bushings? If so what is your opinion and are they worth purchasing?

I like them, but then again they're all I've ever used. They came with my Lock-n-Load press as a standard feature.

yes easy die changes without messing with the die, also a small amount of play helps with alignment if die, ram, and/or shell holder are not perfectly aligned. I load very accurate ammo with mine
