You beat me to it. Been using Safety Seal kits since about 1986. Have purchased probably 15 commercial kits and given them to family & friends.

After Hurricane Andrew in South Florida, I had to patch my service truck tires ad naseum due to the road debris. Between the Safety Seal kits and the cans of air (which I bought by the case after Andrew) I have become a firm believer in the plugs.

Yes, I've heard and read a lot about why you should use the patches, however I've never heard of any issues with a properly installed Safety Seal plug. No affiliation, just a VERY HAPPY Safety Seal customer. YMMV
