No instructions included. Tried a strip and it came loose in the tire. Another inserted and it bent the insertion tool. Don't think it will work. Let's wait and see if it holds air after a short tire run. That doesn't seem good to me now. Will return and update after the plug has time to sit on the bus. I like that I patched my tires when I was younger so I knew how to do it. The insertion tool had to be a heavier metal and smaller shank so it could slide along with the connector strip and pull back out after winding so it wouldn't fly out of the patch. The time will show. I'm holding my breath for now. 12 hours have passed.
