Anyone ever used one of these?

Over the past week I replaced all but the secondary bank 1 O2 sensor, which I replaced some time ago. I realized I didn't use any anti-seize on it so I removed it to put some on. The sensor did not come out easily and several of the threads were all messed up. I'm going to order a new one but I assume I'll need to use one of these thread chasers before installing the new sensor. I've just never used one of these and have no experience with them.

Are they really as easy to use as they sound?

Just use the proper socket and have good leverage when using it. These just basically retab the threads so they are correct/repaired for the new sensor. If the threads are damaged, that is what you need. Make sure its the right re-thread tool.

Yeah, I'll need to clean out the bung threads before installing the new sensor for sure so I think this is exactly what I need.

I've considered replacing the sensor with a Bosch universal but I'd prefer to have the Bosch OEM fit replacement with the wire and connector. The only problem is I'd have to order the OEM fit sensor and wait until Thursday or so for shipping. Any reason I couldn't plug the bung after re-threading and drive the car? I'm sure my SES light would come on but that's to be expected. I don't think the downstream sensors control anything air/fuel ratio wise.

You should be fine.

The thread chaser worked like a charm and the new sensor went in like butter. Ended up using the Bosch universal but it should be fine.
