I've been using Dynaplug since the early 90's and have repaired 15 or 20 flat tires on various vehicles for myself and friends. Most repairs required only one plug, but in some cases 2 or 3 plugs were required if the hole was from a larger object. Not a single repair has leaked, including several run-flat tire repairs. This product just works. Repairs are carried out on site without removing the wheel from the vehicle. This fact allows for quick repairs to get you back on the road and possibly out of a dangerous situation. Anyone can repair. It is not necessary to "rasp" the hole first, which can be difficult and unnecessarily enlarge the puncture. I like that the forks are separate; a nice improvement over the early packaging which sometimes caused a sticky tangle when the forks stuck to the packaging or each other. I think plugs are overpriced for what they are, but in terms of convenience, ease of use, and the ability to repair almost anywhere, they're worth it. pull out the interfering object. Consider having one of those little 12v air pumps in your car, also in case you lose too much air. A decent pump is cheaper than replacing a tire that has failed due to under-inflation. I personally use the CyclePump brand, but you pay well for exceptionally high quality, so other options may be better suited to your needs.
