The product worked as advertised. I had a small screw in my tire and used this product to plug it. Everything was immediately sealed and seems to be holding up. However, there is one issue you should be aware of. The screws are quite small and are coated with a substance that makes them very slippery. This makes it easier to screw the screw into the tire, but also makes it more difficult to hold it in place when screwing it in. When using this, do so in a well-lit area if possible. as the screw is hard to find if you drop it.
