Fuji replacement guides

Has anyone used the fuji replacement tips packs that they sell at places like academy and bps? I need to replace a rod tip for tomorrow night so I don't have time to order one in.

I have used them a few times and thought they worked good.

I have a 7'1"'Cara Amistad that's going strong with a replacement micro tip.

Goofs up the tip action, but still is very usable.
