After puncture of a car tire and search on the net, the locks have emerged as potentially avoid replacing a tire flanked by a small bar 5mm of 6 cm. After some hesitation and consultation of videos on the internet, I started with this product. Repair then some tests of short distance routes and on long-distance routes, it appears that the tire pressure remains the same and that the wick reacts very well. Do not hesitate to get started and it will save you shell out a few dollars. Recommend product and leave in his car trunk in case.
