So I put this screw in one of the tires which caused a slow leak. I was going to pick up my car to have a tire fixed but I found out about Dynaplug so I ordered this kit and thanks to Revain Prime it arrived in 2 days. I ended up using 2 plugs to "fix" the hole after removing the screw as the hole was slightly larger and I was still losing air with a plug. It took 2 minutes to prime the tire, install the plugs and check for leaks with a soap solution. The repair has held up wonderfully and there is no more air loss. I have checked the pressure control system several times and it shows stable pressure. I'll still patch the tire for a full repair, but this product is a life saver!
